Continuing work on the Croshaw family means their founder, Raleigh Croshaw now has three wives, one unknown, one listed as "Unity Powhatan" and one listed as "Ursula Daniels." There are no documents to support any specific wife, but two men, Joseph and Richard Croshaw are pretty well accepted as his sons, so there must have been a woman involved.
A patent was issued to "Captain Rawleigh Crashaw, of Kequotan, gent., and ancient planter," about 1623. The wording of the patent has led to confusion about his wife since it reads "due for his per. adv. and trans. out of England of his srvt & his wife, whoe came in the Bona Nova in 1620 and 25 Lbs. adventured &c." [1] The land patent states that he had been in America continuously for 15 years and no wife is named in any records.
To me, the logical conclusion is that Raleigh's wife was already in America, that his children were born in America, and the wife listed in the patent was the wife of the unnamed servant. No wife and/or children are named in any records from the period including his estate administration. They are not on the 1623 census or 1624/5 muster so it's probable they returned to England at some point. The sons do not appear in Virginia records until the late 1630's; they were apparently well-educated, so had not been living in Virginia.
There is no documentation to support the existence of "Unity Powhatan." If a prominent Jamestown settler had married a daughter of Powhatan prior to Pocahontas' marriage to John Rolfe it surely would have been noticed and recorded. No list of Powhatan's children includes anyone named "Unity."
There is also no documentation to support the existence of "Ursula Daniels" either. She only seems to exist on Internet, sometimes called Unity, or Ursula Unity, sometimes conflated with "Unity Powhatan."
At the very least it seems these two profiles should be merged into one clearly marked mythical woman (since it seems likely that she will just be recreated if she is merged away) and detached as spouse of Raleigh, leaving "Unknown Unknown" as his only spouse.
