The White Family Research Project (https://www.wikitree.com/wiki/Space:White_Family_Research_Project) has been actively pursuing a consolidated effort to identify and document the progenitors of the numerous inhabitants of Colonial Virginia and the North Carolina Tidewater Region that have carried the White surname. Y-DNA Family Line Summary research to date appears to validate the working assumption that the White Family Quaker line in Virginia/North Carolina has its roots from the same family as the immigrant John White d. Abt. 1673 (https://www.wikitree.com/wiki/White-145) who is known to have traveled to New England in 1638 becoming one of the earliest of the White surnamed descendants in that region, initially settling in Salam and eventually moving to Lancaster, MA.   John White d. Abt. 1673  has been documented to Thomas White (bef. 1549) from Somerset, England (https://www.wikitree.com/wiki/White-433) as researched by Almira Larkin White in her 1912 genealogy "Ancestry of John Barber White and of his Descendants".  

Additionally, early research on the structure of the White Family Quaker lines that appear in Mrs. Watson Winslow's book “The History of Perquimans County” and also noted by Currituck County White researcher General John Elliott Wood in his chart “Branches of the White Family”, have been largely validated, although the utilization of modern Y-DNA testing tools has suggested some re-grouping and realignment of several of the lines depicted in this early research.  One of Wood’s more controversial claims concerning the origins of the line, from his September 4, 1955 article in The Virginian-Pilot and Portsmouth Star entitled “The Whites of Tidewater: A Study of Man's Growth in the New World”, (https://www.wikitree.com/photo/jpg/White-70078-4) concluded that "William White, born in England about 1580, was one of the 107 men at Jamestown in 1607. He was buried in Elizabeth City County 12 September 1624 leaving three sons: John, born 1609; James born 1611; and Henry born about 1615”.  This claim will require additional research, although the original certainly appears possible.  Ms. Winslow postulated a similar origin story. 

Y-DNA analysis supports a convergence to approximately two hypothesized “unknown” generations which very well could support a conclusion there was a “William” in early colonial Virginia that could have had sons John, Henry, and James, and John b. 1609 was the father of John White d. 1719 Isle of Wight.    However,  to date no Y-DNA evidence has fully supported the conclusion that the hypothesized John White b. 1609 and Quaker Henry White b. 1615 were brothers.  More testing along the Henry White will be required and is currently in process.
