This is a very old post, but just in case your still looking. This may not be the correct lineage, but it seems to fit. I have much more than this, but I'll only write enough to see if it is the same lineage.
I have brothers: George Warson b abt 1868, d 1918 Elonzo James (Dick) Warson b 23 May 1870, d 1929
Parents: Martin Van Buren Warson b 1839, d 1883 Lydia(Siddie)Hackard b 1841, d 1918
From the Ia. / Oh. area.
I come from the Elonzo brother, G-Grandfather. Hope you get this and let me know if you need more info, Ron.
