The following information comes from the Surprise family CD-Rom created by Janet Umlauf:
Sarah (Sally) SURPRENANT (SURPRISE) was born in 1827 in L'Arcadia, Quebec, Canada. This info is according to a website for the Stilson families. . . . We were under the impression that none of the early children survived. The birthplace cannot possibly be true as Peter and LaRose were not married until they both lived in NY. Also, Peter was not living in Quebec because of the dispersion. He was not even born there either. So, either Sally is the child of cousins and not Peter and LaRose, or she was born elsewhere. I am trying to corroborate this info. I did find that her son Schyler did live for years in Lake Dalecarlia. Whitey Stilson had a barber shop in his house on the Cedar Lake Road going into Lowell. We think this is the same person. She died after 1870.
[NOTE -- in an article about Peter Surprise, Sallie Stilson is specifically mentioned as being born to Peter and Rosanna Surprise. She predeceased her father.]
