I would love to get some information regarding Isaac. Searching the Weyerbacher tree is difficult because of all the name changes. My gggrandfather was Jacob Bitz Weirbach, who sas born 2/26/1843 and died 2/28/1897. His father was listed as William-the birth certificate is in German. He is supposed to have decended from Isaac Weyerbacher but I am having difficulties bridging the last couple of generations.
