Samuel Fitzgerald - Bartlett H Fitzgerald's son
 

Looking for information on the descendants of Samuel Fitzgerald. He is listed as the son of Bartlett Hawkins Fitzgerald of Nelson County, VA. Seems like there are two camps of when Samuel was born. Some claim 1790 with no supporting documentation and others claim 1810, also with no supporting documentation. Half also show him married to Mary Harper, and other half to Elizabeth Ryan.
Anyone have any documented or substantiated descendancy? I'm trying to track down living male descendants for a Y-DNA project.
