My grandmother's (Lena Johanna) sister (Ella Lissa Welke) married a man by the name of Fred Brust. They had one son (Paul) that I know of and have a pic of. This pic was taken at the Welke home in Council Bluffs, IA in/around 1919. Paul looks to be about 5 years old in the picture. Lena & Ella's parents were William Daniel & Pauline Christina. Is there any connection here?
