I am doing research on the family of Ira MAYHEW & Margaret Hamilton HALLIDAY who married Apr 15 1838 in Horton Twp, Renfrew, Ontario.
Amongst their children were some of the names that you listed ~
Joseph, Margaret, John, Charles, James Halliday, Ira, Louise, Elkanah, Jane, Mary Ann, Lyman P and Charlotte Matilda.
Ira born 1823 was in Oakland, Brandon Manitoba as of 1901 Census and his wife Margaret died in Vancouver BC in 1922.
Daughter Charlotte died in 1936 in Edmonton AB.
Daughter Jane married George Ralph WATSON in 1895 in Oakland, Brandon MB and died in 1898.
Ira's brother was Elkanah MAYHEW born 1836, married to Annie ARMSTRONG and they had a daughter, Maude Mary who married an Alfred Pike WHITENAY and moved to Winnipeg where mother Annie Armstrong MAYHEW died on Oct 29 1910.
I would love to find descendants of these many MAYHEWs and welcome any help or ideas or input :-)
