I have some of that info in storage and will check later for more. What I can tell you. I do not know Rebecca's middle name or her parents. She was a Dumond (Diamond on her marriage license). She had a sister Sarah Dumond (DeMond)that married a Louis Guise (I think in IN) and a brother William H. Dumond- who lived in Indiana.
I was researching the western side of Indiana- and the county and neaby counties that some of these Dumond were in briefly, I came across only 1 William H. Dumond that seems to fit with my Rebecca.
This William H. Dumond has a son named Robert.Robert is the person someone has a few years earlier was looking for. I was hoping that person may have some info about William H. and his parents.
If you need the name of Robert's mother I'll look for it. I think Robert's family were LaPorte, Jasper, Lake, maybe Lagrange or Porter counties. I think Robert moved west, returned to get married, then west or into Canada.
