Your Elizabeth Shepherd (Schaffer) who married Isaac Terhune was a sister to my 2nd great-grandmother, Abigail Schaffer (who also lived in Illinois and married Joseph Woolsey).I do not have records of any children for Isaac and Elizabeth, but I would be interested in knowing this data. I know a little bit about the ancestry of Elizabeth and Abigail, but it is sketchy.Would love to know more. I show a line for Isaac Terhune back to the immigrant, but I assume you already have that. Will be happy to share anything that is of interest to you.
[Shepherd is the English word for German Schaffer.Some of these Schaffer's gradually changed their name to Shepherd over the years.It took me a long time to find Elizabeth's marriage record because I always looked for Schaffer.But I knew, from Abigail's descendants, that the husband was Isaac Terhune, so I finally figured out that it was the record for Elizabeth Shepherd.]
