My mother does the same thing , she is in the DAR and Daughters of the Confederacy . She was tracking down part of the German side and came to a stump , as the spelling in the last name was different . I was in contact with a guy that lived in Germany , and told him about it . Turns out that the current spelling is incorrect , as it was Anglicized , he told me the proper German spelling ……………….BINGO ! my mom was off and running again . So f you run into trouble , be aware that a lot of nationalities changed the spelling of the last name in order to make it easier for english speakers to pronounce .
Oh ! by the way , that song is a Confederate song with the words changed lol , the real song is ‘ I’m a good ol rebel ” .
