I think we may have a connection.My husband's grandfather was Henry Louis Hamlett, born July 5, 1905 in Milton, NC.I found Henry's name on the SSDI, and sent for his application.It states that Henry's father was William Smith Hamlett, and his mother was Elizabeth Taylor.
I don't have much information, though, on the family.My husband's father passed away almost 11 years ago, and there had not been much communication with his family.I have been told by my mother-in-law, though, that Henry Louis had siblings named Jessie (male), Dot (also male - your Dotson?), Jack, Lennie (Maggie Lena?), and Mary.
I have not been actively researching the family, as I started out with my own lines, and they have kept me hopping.However, I would appreciate any information that you would share with me - that is, if you think these families are one and the same.
