Yes it certainly does mean we are cousins.I have pictures and stuff on Ednas side of the family but not the Thaden side; with the exception of Henry, Wallace, & Gene, Thaden. Any Thaden family member beyond Henry would not be related to me. I am only related to the The Thadens under Henry and Edna. When I learned Ednas middle name was Etta, I thought that was neet because that means Pearl named my grandmother after her sister Edna since my grandmothers name was Helen Etta Simmons. Do you have the wedding picture of Edna & Henry Thaden? If not I think I do and that would acompany your framed wedding certificate nicely.
