Ray Here is what we can demonstrate from the records Adams - unknown, probably England to MD / VA
Dr William Adams - dies 1657 @ NU Co. Widow remarries to Thomas Brewer, has several Brewer children.
John Adams of Westmoreland and later Lancaster Co. Born ca 1627-1632 (by records), dies 1699 Lancaster Co. At least three sons - likely ancestor of Absolem Adams of Fauquier Co
Thomas Adams of NU Co, bachelor, no children. Associate of Rice and Ashton
Thomas Adams serves as administrator to the estate of William Adams who dies in 1677. John Adams, with wife Katherine sells land in 1701 that once belonged to Thomas.
John Adams b bef 1658, m Katherine. Daniel Richard Catherine (b 1690s) ? daughter Susannah (m Richard Nealmes) William (b 1690s) John Adams Jr b 1689 (by later tax records). First marriage probably ca 1705. George b 1709, William b bef 1709, John III (m Eleanor, b ca 1714, ? Nipper b bef 1730, possibly dead by 1752.
Other Adams in the area who cannot be connected directly to the above Gabriel - b 1685 - had children Philip, Gabriel Jr, John, Silvester, Susannah, and two unknown daughters. Sylvester m a woman named Ann, had a son George, migrated to Dan River area. Benjamin b ca 1710 or earlier ... married widow Elizabeth Waugh Gregg. No children identified. James - witnessed a land sale for John and Katherine in 1704, found later at Westmoreland Co. His relationship is uncertain.
Richard - a Richard Adams has children at St Stephen's Parish in the late 1690s. Richard Adams is found living at the home of John Adams Sr in 1724. Richrd Adams Sr and Jr are found at Dettingen Parish in 1747, but never own property at Brent Town. Richard Adams Sr of PWCo was born ca 1701 (exemption from taxes) and petitions the parish in 1760 for custody of an orphan Nipper Adams (b no earlier than 1745).
There are no actual wills in this family until much later. We can connect John Sr to William, George, John Jr and Nipper the elder by tax lists, land deeds, court cases and other documents. The other named men lived in the same area and may easily be relatives -- perhaps children of John Adams of Lancaster Co, uncle to John Adams, carpenter of NU Co.
While the baseline DNA proves the very close relationship of these men, there are sufficient slight variations that if others step forward we may be able to determine the precise relationship of these men.
