Jeremiah and Barbary appear to have had at lwast 5 children. Gabriel, Nancy, Jeremiah Jr, a son whose first name is unknown and James Patrick. Many people list the unknown sin as Henry but there is evidence to support this claim. And it seems to be the result of a missing identification. There is a marriage certificate in Ohio cty Va (now W Va) for a Henry and Martha Foley. But this couple remained in the Ohio cty area and had several children and appear on US Census.
This unknown Foley did marry a Martha. Her maiden nane is unknown. They had 4 children, Andrew Jackson, Wesley, James M and Linville. Martha and her sons first appear in records on the 1830 census. While only the head of household is listed on this census their are other people listed which match up with 2 widowed daughter and laws and their children which match up with the their known children. 4 years later both Martha and Barbary Jr. died within weeks of eachother. There are court recirds disposing of Martha's property and appointing a guardian for her minor children Wesley, James M and Linville. The Guardian was John H Walker. His relationship to the boys or to Martha is unknown. Linville changed is name to Walker. He martied and had several children so at this point this branch of the Foley tree includes the primary surname Walker.
The unknown Foley son appears to have died before the 1830 census and most likely sometime in 1829. There are no known records of either his death or martiage to Martha. The fact Martha either moved in with her mother in law or was already living with Barbary Jr, strongly suggest that Martha's husband is the unknown Foley son.
There is some information that Henry Foley had additional children beside Luke and Bartholomew. There is some documentation for Bart, land deeds and a will. The Will establishs beyond any doubt Bart's and Barbary's Sr chlidren were all female as they are listed in several Court documents. This also help to establish that any male children in the Patrick/Henry county area were most likely the product of Luke.
However, the relationship between Bart, Luke and Henry is at best a guess as there is no record of existence prior to when Luke and Bart started buying land in Southwestern VA. If there is any documentation that establishes this relationship please share it.
