My grandfather was Ross Estey (died 1994) from Kilburn New Brunswick (near Perth Andover). His wife was Glenna Rideout from Kincardin? Most of the Estey's live in the Zealand /Keswick Ridge area north of Fredericton, NB.
My dad has the complete family history book dating all the way back to Mary Estay one the Salem witches, she was from Topsfield, MA.
E-mail if you would like more info.
There are Estey's from the Saint John, New Brunswick Canada area as well. Although not directly related they are connected from way back.
