Believe it or not I did contact NNYACGS years ago and had the birth and christening dates for my family. There were alot more children for Gilbert Rock and Margaret Bisson then I have listed. The names were all in latin of course but all the same parents and birthdate a year or more. I had a list of about 16 that were born in Plattsburgh, but I don't have that list any longer so I will have to contact them again. Also I believe they had a few in Quebec as well.
