Like so many families no one in my parents, grandparents, or great grandparents families kept records of any kind. The only thing I have are a few names and cannot find anything from the German side of the Atlantic.
My GG Grandfather was Jacob Schatz (who may have been a rabbi) He had a children named Max, Charles and Herman and a sister named Elsie.
My G Grandfather was named Herman Schatz who had children named Harold, George, Dorothy and John.
The time frame for birth of Jacob would have been 1850's. Herman was born in 1874. Harold was born in the U.S. in 1911.
Jacob is supposed to have been from Speyer, Germany. I don't know if he came to N. America, but I have not found him coming through Ellis Island.
