George Kappler is my Great Great Grandfather. Mamie was one his children. Mamie was his daughter. I have a good bit of info on them. I will send you a link so you can view my tree. Would love to take a look at yours as I hit a bit of a brick wall with Frederica. I could not find a last name for her. Even if you don't have it knowing when Gertrude was born would help me find Frederica's death certificate.
