I am doing some research for my mother in law. Her maternal great grandfather was Jacob Berger. He was born in May of 1869 in Austria. He married a Kate who was born Dec. of 1865 in Russia. They had at least one child. The one I know about is Jake E. (Jacob) Berger. he was born in 1897 in Dickinson, N. Dakota. Does anyone have any info on Jacob Sr or his wife?
