Tom, I have nothing on her ancestors. I do have from burial permit in Vergennes, book 8 pg 165, that Caroline died in Bristol VT 6/20/1916. Bristol should have death record which would have her parents. Timothy and Caroline (Ikey) Wissell are buried in Prosect Cemetery in Vergennes section B Lot 25.
I went to that site and didn't find any info but will go back again. It was French and I had to have it into English and didn't seem to find the right church.
