Looking for information on my Great Grand Mother, Rose/Rosa Wittke. She married Perry Pemberton. Children;Gussie, Leonard, Dollie/Dolly, and a son who died at age 12 of an accidental gunshot wound. Perry and Rose/Rosa seperated sometime after 1913, and she eventually settled in Marietta, Ohio with Leonard and Dollie/Dolly. Any information would be appreciated.
