Edward was a mariner, resided Spanish Point, Bermuda (Edward Dunscomb will dated 2/3/1790, probated 10/16/1790. Bermuda Archives Book of Wills, Book 10, pg. 372, film 288).In 1773 he owned a ship, the 60-ton "Peggy" (Bernhard, Virginia. Slaves and slaveholders in Bermuda. Columbia : Univ. of Missouri Press, c1999, pg. 267].

It is possible that this Edward is not the son of Edward and Hannah, since that would seem to make him quite elderly to be getting married in 1768 and having children about 1780. However the 1733 of Edward husband of Hannah mentions sons Edward and William, and the will of Edward died 1790 mentions a brother William. The 1733 will also mentions a daughter Annah and the 1790 will mentions a sister Anne Gilbert. Also the fact that his wife Christiana died so long after Edward indicates that he may have been much older than she when they married, although the possibility certainly exists that there is a generation in between I am not aware of. Their son John also named one of his daughter's "Sarah Christianna" possibly after his mother, or grandmother.

The birth order of Edward and Christiana's children is uncertain.

The book "Slaves and slaveholders in Bermuda 1616-1782 by Virginia Bernhard (c1999, Uinversity of Missouri Press) makes numerous references to the Dunscomb family, including Edward and his brother William (note I disagree with the author's assertion that Edward and William were sone of Thomas Dunscomb and Prudence. I corresponded with her in 2009 and she seems to base this opinion on the fact that Edward and William were brothers (1790 will of Edward Dunscomb), that they shared a pew at St. John's Church and lived on the same Pembroke property in 1789, and that Thomas and Prudence had a child named William. However I find no record they also had a son named Edward; whereas the 1733 will of another Edward Dunscomb notes surviving sons Edward and WIlliam):

pg. 242 in discussing seating assignments at St. John's Church, Pembroke: "A surviving record of the pews for 1781 lists the following names, which include the parish's most prominent men: Cornelius Hinson, Samuel Saltus, Joseph Wood, John Blackbourn, Nicholas Albouy, Nathaniel Numan, William Leaycraft, William Dunscomb, Edward Dunscomb, Peter Godfrey, Horace Wood, George Darrell, Benjamin Pitt, David Eve, Joseph Stowe, Henry Butterfield, John Beck, Benjamin Dunscomb, William Morris, John Wainwright, and Thomas Whitney."

pg. 245 discussing the 1773 Pembroke Parish census: "... there were four Dunscombs, including Edward, the owner of the 60-ton sloop Peggy, and William, who owned the 50-ton Jean."

pg. 267: "The Dunscomb family, whose matriarch, Hannah Dunscomb, had owned 50 acres in 1663, by 1773 had only two acres - but they owned two ships: Edward Dunscombe had the 60-ton Peggy, the largest of Pembrokes 11 vessels; his brother William owned one of the next largest, the 50-ton Francis. The Dunscomb brothers both married into the family of Pembroke shipwright Peter Godfrey, who lived near the Dunscombs at Spanish Point. Edward Married Christiana Godfrey in 1768; William married Love Godfrey in 1773. Christiana and Love Godfrey were sisters of John Blackbourne's wife, Susanna. Edward and William were the sonce of Thomas Dunscomb and Prudence Waterman, whoe 1717 marriage had united two longtime Pembroke landowning families. Both Dunscomb brothers made their living from the sea, and both kept what was, by Bermuda standards, a substantial number of slaves. Edward was listed in 1773 as having 10 slaves: three men, three women, two girls, and two boys - presumably three family groups. The three men, plus one white sailor, were crew members of the Peggy. William Dunscomb had eight slaves - three men, two women, a boy, and two girls. No doubt William, as owner of the Francis, also had sailors, but that part of his listing in the survey is damaged and unreadable.
Besides the Dunscombs, Stowes, and Woods, all of whom lived within a half-mile radius of each other at the west end of the parish..."
