This is the one I referred to;
1870 census, Van Buren Twp., Union Co. AR, page 16
Warren, Thomas 36 MO
Augusrus 25 LA
John 3 AR
James 2 AR

I did my research on my Warren family many years ago (before computers) and don't really remember where I found what, but I was very careful about documentation at the time.
I'm 73 years old and discarded most my documents, 4 file cabinets full, long ago.
If you can offer proof, fine. Otherwise, I keep what I have.
