The Ibbotsons were from Sheffield, England and Henry and William founded the famous Globe Works (crucible steel) which is now on the Register of Historic Places in England. Henry came to America and married Ann Francis Darling and gave his share of the Globe Works to his brother (e-mail from Mary (Reed) Earl, 1/24/2014).
The first known of this line was Henry Ibbotson. a native of
Sheffield, Yorkshire, England. He was descended from a long line
of country gentlemen of several ancient and remarkable families.
His immediate ancestors were country squires. Henry was born
on June 19, 1797. He grew up in his native city and established
the great house of Ibbotson Brothers in Sheffield. The firm was
called the Globe Works in which he became the senior partner.
The business was principally the manufacture of cutlery.
It is not known what inspired him to do so but he came to New
York some time prior to July, 1833, being then unmarried. He
may have come on a business trip in the interests of the firm. He
must have liked the country for on July 23, 1833. he married
Anne Frances Darling of New York.
Henry retained his interest in the firm of Ibbotson Brothers
until some time between 1835 and 1840, when he made over the
business to his partner and honored associate, William Ibbotson.
who was his cousin and his sister's husband.
Henry now being married and deciding to stay in America,
threw himself into the life of the country and made his influence
felt in the manufactures of the United States. He was instrumental
in starting wire working in New York City; screw making in
Poughkeepsie, N.Y. ; established the first cutlery works at Peek-
skill, N. Y., and other enterprises of the kind. He was also a
judicious investor in real estate. He evidently believed in the
future of the country for he bought and sold several large proper-
ties in the cities of New York, Boston. Philadelphia and Chicago.
He was also a social favorite, being a friend and intimate of
many distinguished men of his day. Among his friends he num-
bered the Right Reverends Manton Eastburn and Charles P. Mc-
Ilvane. Louis Tappen. Esq., the poet James Montgomery. Mrs.
Lvdia Sigourney with whom he corresponded. Governor, the
Honorable William W. Seward, besides manv others.
Henry Ibbotson died of cholera, on August 27, 1849, at the age
of fifty-two years "having lived a godly life, full of honors and
enterprise."
