If you go to this fantastic website: http://memory.loc.gov/ammem/repehtml/repehome.htmlhttp://memory.loc.gov/ammem/repehtml/repehome.html You can browse religious petitions from the 1700's in all Virginia Counties. I browsed through two tidewater counties (King And Queen and Caroline) that were once a part of Essex County and discovered Nicanor Pilkinton's signature (looks like Nicanah Pilkinton). The petition was dated October 16, 1779 and concerned the parishioners' opposition to dividing Drysdale Parrish which was in both counties. The Caroline County petition is just a hand written copy of the King And Queen County petition including the exact same names. The copy verifies that the name on the first petition is Nicanor (although it mispells the last name as Pilkerson). This places Nicanor in the Essex tidewater area where Ambrose was in the 1750's. I believe this helps confirm Nicanor and Permenus' relationship as well as makes him the likely son of Ambrose.
