Jacob Kopf (1837-1904, b. Wuerttermberg, Germany) is my great-grandfather. My grandfather was Jacob Kopf, who died in 1954. My father was Ralph Jacob Kopf, who was born June 29, 1927 and died November 4, 1993. If you want to know more about this branch of the family tree let me know. I would like to know more about the lineage prior to Jacob (1837-1904). Thanks.
