Hi, Don't know if this helps but my Great Grandfather was Jean Baptiste Garneau. When I was about 8 years of age my family went to visit him and my Great Grandmother in Lewiston, Maine. They had three daughters
Germaine Garneau (my Grandmother married name Deschenes)passed April 2002 in Connecticut. Her husband Irenee J. Deschenes passed in 1973 Connecticut. They had three sons. Eldest son Renald J. Deschenes (my father) passed October 1966 in Massachusetts. The other boys are still alive.
Jeanette/Genette the youngest of the three is still alive and now living in New Hampshire.
Sorry I don't have any other info for you but I myself am searching for name's.
