I sure wish I could help you with your line, but I don't seem to find any of these in my data base.

The only Allen Upchurch I have was born about 1779 and is the son of Harmon Upchurch. They were in North Carolina before many of them struck out and ended up in Arkansas. From there they made their way to Oklahoma and Indian Territories... in the 1890s.

I'm not familiar with any of the SC Upchurches...
