I discovered Alanson Lockwood has 2 sons named Henry Alonzo b 1837 (my GGF) has 1 source 1850 US Cen. & 1 child my GM; & Henry Clay b 1838 w approx. 17 sources & 4 children (would be my GGU). This could impact a number of Trees if the wrong Henry has been used. Another fact is that Henry C. spouse is from NY. Henry A. & spouse are also from NY. Alanson Lockwood's WikiTree add. below.
