William was a tinsmith in his early life. Later in the real estate business. He came to the U.S. circa 1878 with his widowed mother who remarried a man surnamed Wurster. William had a half-brother named Frederick, and a sister named Frederika who married a man named Ernest Bolm. Fred Wurster was a Methodist minister. and performed the marriage of William and Katherine.
The 1920 federal census shows his emigration as 1858 but that census also states he is 57 years old, implying a birth year of about 1863.
William's daughter Lydia wrote a letter to Edith (Schweikert) Dunscombe June 16, 1977 in which she stated that William's ancestors lived in Austria. They became Protestants and could not agree with the Catholics, so his family moved to the Northern part of Germany, the Black Forest, and when a young man he and his mother came to New York when his father died, and settled in Brooklyn. She states that her father's people were titled. They became Methodists and William met his wife Katherine in the church. However U.S. census records indicate he was born in Wurttemberg, southern Germany. The 1920 census also states both his parents were born in Wurttemberg, Germany.
Received an e-mail from Darlynn Frodsham (Feb. 15, 2001) indicating she had found many Schweikert and Hansler (Hanssler) entries in Boll, Germany, though none for a William (Wilhelm) born 1863. In a follow-up dated Feb. 28, 2001 she states that Boll may now be called "Bad Boll," not far from Goppingen, Hozlheim, Heiningen, Hattenhofen, Ohmden, Kichheim, Uhingen, and Weilheim, apparently all in Wurttemberg.

Naturalized March 12, 1885, Kings County, New York, Court. Witnessed by "Frederick Wurster."
Under "Schwirkirt" in 1900 federal census.
1900 census has his birthdate as May 1863. Death certificate has November 1, 1862.
Edith Jean (Schweikert) Dunscombe stated his name was William Frederick, but the records in Germany have him as Wilhelm David.

William was party to a law suit settled in 1894. His step-brother, Christian Wurster, died April 30, 1890, four months after his wife, Marianna (also cited as "Marie" and "Maria"), who died January 1, 1890. Christian had taken out two life insurance policies naming his wife as the sole beneficiary. Christian's will, dated April 15, 1890, left the proceeds to his brother-in-law, William Schweikert. Interestingly one of the witnesses to the will was named Andrew Hansler. the same name as William's fathr-in-law. The will is avaiable at ancestry.com, and the court decision is available in "The Miscellaneous Reports, Cases Decided in the Courts of Record of the State of New York, vol VIII, 1894."

Waldheim v John Hancock ML Ins Co
New York State Reporter Vol 59 N YCityCt

McCarthy J. This is an appeal from a judgment in favor of plaintiff entered upon a direction to the jury to find a verdict for the plaintiff for Section 400.19. The defendant in the years 1884 and 1885 issued two policies both on the life of one Christian Wurster on his application he paying the premiums for the benefit of his wife Marianna Wurster not to her administrator, executors, assigns, legal representatives etc. but payable only to Marianna Wurster her name being the only one mentioned in the policy The policies were delivered to and held by him until his death The beneficiary Maria Wurster died intestate about January 1 1890 before the insured Christian Wurster who died about April 30 1890, four months after the death of the beneficiary, the wife retaining possession of the policies up to the time of his death the plaintiff's intestate never having had possession of them, he Wurster having paid the premiums up to the time and after his wife's death. There was no issue of the marriage between plaintiff's intestate and the insured and plaintiff is a son of the intestate by a former marriage and no relative of the deceased. The necessary and ordinary allegations of the appointment of administration were alleged. To this state of fact the defendant demurred as not alleging facts sufficient to constitute a cause of action which was sustained at a special term of this court but reversed at a general term Chief Justice Ehrlich writing the opinion which was filed March 10 1891 and order and judgment of reversal entered March 16 1891. This general term holding that upon the face of the complaint no action appearing showing an intent of deceased to have the policy go elsewhere than to the personal representatives of the wife the action was properly brought by them. Adopting the decision of the general term the defendants thereupon paid $132 costs and answered over denying that any policy had ever been issued to the plaintiff's intestate Maria Wurster and alleging an assignment of the moneys under the policy to William Schweikert after the death of Maria Wurster the wife and also a last will and testament by Christian Wurster the insured specifically bequeathing the insurance money to William Schweikert and that the moneys had been paid to the executor under the will. On the trial the defendant attempted to introduce evidence to meet the requirements of the general term opinion and carry out the idea of and acts of Christian Wurster which would have showed not only an intention to have this insurance money go contrary to the implied intention of the law i.e. to the personal representatives of the wife but did actually convey transfer assign and bequeath this insurance money to William Schweikert, a person other than a representative of the wife viz a step brother of the deceased insured. The justice directed a verdict against objection and exception of the defendant and refused defendant's request to go to the jury on the facts as to the intention of the insured and also on the question as to who should have these insurance moneys. This is not a case where it is provided that in case of the death of the wife before the insured it shall go to the children or her representatives nor is it the case of the wife insuring the life of her husband for her sole use and benefit and thus in my judgment not affected by statute law. The intention of the insured when he took out this policy was to make a provision for his wife only and no one else in case he should die before her. In Baker v The Union Mutual Life Ins Co 43 NY 286 Allen J says the insurance was affected by the husband for the benefit of his wife and as a provision for her in case of his death. He was the party contracting with the defendants and the consideration for the agreement to insure proceeded from him not from his wife. The statutes of this state authorize a married woman to insure the life of her husband for her own benefit and declare that the insurance shall be payable to her free from the claims of the representatives and creditors of her husband but the exemption is restricted to policies upon which the annual premium shall not exceed $300. Laws of 1840 chap 80 Laws of 1858 chap 187. But the plaintiff had an interest in the life of her husband and an insurance procured by him for her benefit is good at common law. The policy would not be void as a gaining policy. This policy does not purport to have been effected or procured by the wife or at her instance. The deceased had an insurable interest in his own life and could lawfully insure for his own benefit or in favor of any one having an interest in his life as wife, child, or creditor and could secure the insurance to the party intended to be benefited either by taking a policy naming such intended beneficiary or by taking a policy payable to himself or his representatives and transferring it. In Olmsted v Keyes 85 NY 598 Earl J says "This policy was taken out by Lester for the benefit of his wife. It was an insurance on his own life for her benefit. While one cannot insure a life in which he has no interest every person can insure his own life for any sum upon which he can agree with an insurance company. A life insurance is not like fire insurance, a contract of indemnity but a mere contract to pay a certain sum of money on the death of a person in consideration of the due payment of certain annuity for his life, Bailey v The India and London Life Ass Co 28 Eng Law Eq 312 Raivls v Am Life Ins Co 36 Barb 357 S C 27 NY 282 Ins Co v Bailey 13 Wall 516. Like every other contract to pay money such a policy is a chose in action with all the ordinary incidents of every other chose in action. It is abundantly settled in this state that one who takes an insurance upon his own life may make the policy payable to any person whom he may name in the policy and again at page 602 he says "All the choses of the wife not reduced to possession during the joint lives by the common law passed to the husband on her death - all without any exception - and there is no authority to the contrary and this is true whether such choses are then payable or are mere reversionary or contingent interests payable at a future day or mere possibilities lie may then release them or take payment of them without administration if he can get payment. If administration is needed to reduce the chosen to possession he is entitled to it and if there are no debts the administration is solely for his benefit. If after his wife's death the husband does not release, assign, or reduce to possession her choses in action during his lifetime then after his death his personal representatives are entitled to administration upon them for the benefit of his estate as part of his assets. The wife's interest in this policy was a chose in action. At her death it passed to her husband. He had a right then to assign transfer or will it as any other chose in action. And where he failed to administer on the same the obligation of the insured would be enforceable by the personal representatives of the husband. See Walsh v The Mutual Life Ins Co 133 NY 419 45 St Rep 123. In all the cases where it has been held that it went to the personal representatives of the wife as in Whitehead v New York Life Ins Co 102 NY 143 1 St Rep 344 and others the contract was made with the insurer by the wife on the life of the insured for her sole use and benefit or the insured simply acted as her agent and in almost each case the beneficiary and substitute are mentioned. All these cases and distinctions are clearly and fully discussed in Walsh v Mutual Life Ins Co supra. That is not this case. In determining the question on the former appeal which was on a demurrer to the complaint the court was only passing on the sufficiency of the pleading and did not have before it the contract or policy of insurance or other evidence presented on the trial and which the plaintiff if he succeeds must have before the court as well as his complaint. The one paves the way the other is the substance and material upon which the structure must stand or fall. The evidence and facts not being alike there is not conflict with the former decision.. For these reasons we think the trial judge erred in directing a verdict for the plaintiff and judgment should be reversed and new trial granted with costs to abide the event
Ehrlich CJ and Van Wyck J concur.
