I realize that this is an old post but I just discovered my fathers great grandparents on the 1880 census of Dannemora, NY. His name was
Head, Ezra Menard brn abt. 1852 Canada
Wife, Esther (Desmaris) brn abt 1856 NY
Daughter, Lenore abt 1875, NY
Son, George abt 1876, AuSable Falls, NY.. Listed on his death cert
Daughter, Ellen abt 1879, NY

This is really all I know of them in NY. Believed to have moved to CT & they are listed on the 1900 census in Putnam, Windham, CT as " Minor" Esther is believed to have passed in 1898 in CT. If this is correct, it lists her parents as a Joseph & Sarah Desmaris. Esther's name has been spelled in many different variations as well.
