I think your Frappiers were from Kingscroft. There is even a Frappier Road there. Eva's parents, according to her marriage record, were Ephrem Frappier and Dorothé Turcotte. I found their marriage, at St Thomas d'Aquin in Compton, March 4, 1862. There was no Catholic church in Kingscroft until 1904, so marriages, baptisms, etc, took place in Compton. Or maybe, sometimes, in other parishes. I could not find Eva's baptism in Compton. You could try Coaticook. The Frappier, Gadbois and Dudevoir families were all interconnected. I am looking for Dudevoir connections.
