Do you know when your Henry was born. Mine Approximately 1844. Yours could be a father or? Also, do you know what his middle initial was. Mine was Henry Carl Abel, or Henry Karl Abel, or Carl Henry Abel, or Henry C. Abel, or C.H. Abel. There could be a possible connection to you but we need more information. How about the Wernigerode connection? What is your confidence level of this being the only children? I am not certain of Wernigerode myself but it was one clue I am working on. This clue is based on a photo I have when he was a teenager...photo marked Wernigerorde.
