http://files.usgwarchives.net/va/culpeper/bios/n2000000.txt from the About says:
The record of William III is also rather brief, with a mention that he married Ann Kirk on 10 Feb 1717. At that point, the history shifts to Culpeper, Va.
since the marriage date there is the same as on the Timeline, I will assume the suffix is flexible but am looking for more children than just William Nash, V of Lancaster County, Virginia
William II and William III Conclusions
From this we may conclude that this will belongs not to
William II, but to his son William III. Consistent with
this, we also conclude:
William II married Amey Edmonds abt 1670-1675
William II & Amey had children:
Elizabeth, Mary, Rebecca, William (III), John
William II died 1698
Amey died 1710
William III married Ann (prob around 1691)
William III and Ann sold the Nash Mill 1709
William III died 1719
These conclusions are supported, somewhat, by the in fact
another William Nash married Ann Kirk at about that time
(1717) and as such was at an age that he may have needed to
be educated. Also there is the will of John Nash of
Lancaster in 1734. This John was most likely the one
referred to in Williams will.
This:
so we have
William Nash IV, born prob 1695-1700 (Lancaster) -
died ?
Ann Kirk, born unk (prob Lancaster) - died
married 1717, Lancaster, Va
child: William V, born after 1717 in Lancaster
married Betty abt 1738 and moved to Culpeper
County, Va
