Can anyone give me proof of which middle name for Arlo is correct? A son of Sampson Jefferson Ainsworth,1808-1896,and Annie Jones, 1812-1878. I have two versions of Arlo's middle name, Hendrum and Henderson. This Arlo H.,b.1831,married Hannah Gunter and was killed in the Civil War in 1864. They had a son named Charles Henderson Ainsworth, b. 1860.Another son,Allen Winfield Ainsworth,b.1857, named his son Arlo Henderson,b.1879. By this it seems his direct family used the Henderson middle name. Anyone know for sure?
