My gg grandmother was Christa Lamadelaine. She was born in Canada circa 1818 but at some point after she came to Northern New York her surname changed from Lamadelaine to McDonald. Her maiden name is listed as Scholastique Lamadelaine for some of her children's baptisms but on their death certificates her maiden name is listed as Christa McDonald. I don't know where she came from in Canada but she later lived in Fort Covington, NY and was married to Joseph Marshall who was also know as Joseph Masson
