Hi Laurie,
After alot of research, I think we have a connection. I have Maria in my family tree also. Maria was the daughter of Charles (Karl) Bubolz and Wilhelmina Emke (you have Kemke) Charles had seven children, Mina, Emilie, Augusta, Robert, Maria (Mary), Charles, and Mena.

Charles Bubolz had three brothers Frederick, Ferdinand, and Daniel. Frederick was my great great grandfather. They came to the United States in 1856 from Pommerania.

I have some information on Mary's brother, Robert, but this family is completely lost to our side. I would love to hear how your related.
