Here are a couple of links that were compiled by a Geni profiler, but which seem to give credence to some theories more than others about which Richard William(?) Taylor was the husband of Sarah Barker.
The following records in re: his father-in-law Capt Wm. Barker Sr (ca. 1590-1654) and family, might be worth investigating for validity:
- From the Virginia Historical Society holdings: "Whereas by and after the decease of John Barker [NOTE: This John Barker is not actually identified in the Geni profile; earlier, in the extensive notes, he is described as a son of William, but again, he's not profiled - his demise was apparent cause for Richard Taylor's wife getting an inheritance, it would appear] late of Flowerdue Hundred in Charles City Coun. in Virginia deceased, all that tract commonly called Flowerdue Hundred containing 1,000 acres did lawfully descend and come to Sarah then the wife of Richard Taylor, deceased, and now the wife of Robert Lucy and Elizabeth, wife of Phillip Limbry — sisters and co-heirs with the said John Barker."
- William Barker and his Associates & Company patented 1850 acres in Charles City Co, VA 600 acres formerly called Powelbrooke, now Merchants Hope, had previously been owned by Nathaniell Powell (Powell, killed at Powellbrooke in the 1622 massacre at Jamestown) and was later sold by his brother and heir Thomas Powell to John Taylor of London (This was a renewal of the 11/1635 patent).
- John Taylor, citizen and girdler of London sold in 1638, to William Barker, his interest in "Powellbrooke", which he had bought from Thomas Powell, heir and brother of Nathaniel Powell, killed at Powellbrooke in the 1622 massacre.
