Hiram Zink Baden Germany

I am still looking for Hiram Zink.According to Dora Zink Kellogg's book, he came to America about 1755 and arrived in Philadelphia, PA.He travelled with one brother and met up with another brother, Gottleib.Cannot find anything on him after he arrived.He had one son, who was born after Hiram came to America, but do not know where he was born.Pennsylvania or Virginia?Philip lived in Virginia most of if not all of his life.
Would appreciate any information on Hiram before or after he came to America.
Thank You
Roberta
