I am Angela Hammon and I have two brothers who are Hammon. I see above your last name is spelled Hamman. I did my Dna test on 23andme ,and one of my brother refuses to do a DNA test but maybe the other will. Still need info? My tree is listed here on ancestry.com. The oldest Hammon I have in my tree is Nathaniel Hammon. Then his son William, his son Clarence, then his son Robert , my dad. angela
