Bonnie, Thanks for the response.Does the marriage record in Rhinebeck give any useful clues as to Dinah's parents? If not, I suggest you check baptismal records for her children, as often the sponsors at the baptism aregrandparents or aunts and uncles.
As regards our book, yes John TerBush and Annatie Cooper appear on page 106.This John was a son of Hendrick (Henry) TerBush and Rachel Freer.Our records show that Annatie was probably his second wife and that they had two daughters, Ruth and Jemima, both baptized at the Fishkill Dutch Church.
Jemima was born in 1786; I could see Jemima being altered to Jenny, but the years of birth are different.
Our book would probably be helpful to you, as it has a list of 95 references.For example, our data on John and Annatie come from "10,000 vital records of Central NY 1813-1950", by Fred Q. Bowman.
