This is what I have on my James Allen - don't know if it might fit, but, for what it's worth...
James Allen was born in 1763 in County Donegal, Ireland.(Which would have been in the Ulster Province.)He married Nancy Anne Wilson in Co. Donegal March 16, 1790.She was born August 8 1773, also in Co. Donegal, Ireland.They had 7 children.The first 3 - John, Jane and Margaret - were born in Ireland.The family immigraged to the U.S. sometime between 1796 and 1799 and were living in Virginia in 1799.The couple's 4 younger children - Isabella, Robert, Hanna King, and William Floyd - were born in Virginia.
The dates I have on my James Allen and Nancy Anne (Wilson) Allen were taken from their headstones in Smith County, Tennessee.
I do know that James' son, Dr. Robert Allen, was born in Virginia.James and Nancy's daughter, Isabella, was born in New Dublin, VA on 23 Apr 1799; their daughter, Hanna King Allen, was born in Abingdon, VA on 24 Oct 1806; their son, William Floyd Allen was born in Abingdon, VA on 10 Apr 1813.
It is very interesting that your family has the same names James, Robert, etc...I hope you find a link in here somewhere.Let me know...Thanks,
