I am Linda's niece, and thank you all for posting. It is nice to "meet" you.
The Ballerstein family is gettting bigger and bigger for me,as my tree is around 400 strong. Wilhelm is a son to Gustav Sr. (my GR GR Grandfather) and Dorothea Dittmar, along with Gustav Jr, Otto, Emma, and Herman.(Gustav Jr. is my GR Grandfather.) Dorothea later married Adolph Bornowski and had more children (won't list them now)So yes I believe we are talking with family- If anyone is interested my email is firstname.lastname@example.org.
Kimberly Grosskrautz helped me alot, as she is a member of the Bornowski's side of the family. I could not have done this without her help.
