I'm looking for any information on Christina Maria Zink, my 5g-grandmother. She married Peter Jacobs, son of Hans and Anna (Hansen) Jacobs. I don't have dates, except that Peter died 17 Feb 1778, and was born in Schleswig-Holstein, Germany. Peter and Christina had a son, Johan J. Jacobs, 25 March 1775, and I think that was in S-H as well. Johan married Maria Kroger.
I'm not sure if or when any of these folks immigrated to America, but some of their descendants eventually made to to the area of Davenport, Scott County, Iowa.
Thanks for any help!
