Ulrich Hornecker

I am trying to find info on Susanna Hornecker who married Johannes Heckman, she was born 1745 according to the Records of Dryland Union Lutheran Church, Johannes Heckman died 2 July 1814 buried Dryland cem.He was born in Germany, their son Peter Heckman married Elisabeth Bundstein, I know they had atleast one child Catherine, but am trying to find Susanna's siblings and parents, and any info on Peter and Elisabeth Bundstein/Bunstine/Bonstein Heckman.Elisabeth was sister to my 4th great grandfather Jacob Bonstine that moved to Iowa and is buried there.

Thanks
Tanya
