Margaret McCURLEY/McCURLY was living with the McMasters in 1911
LINKMcMasters in 1901
LINKAlexander McMASTER m Margaret WALLACE on Aug 19 1881
LINKJohn Graham WALLACE was a witness to this marriage
Margaret WALLACE's father is given as Francis WALLACE
I believe John Graham WALLACE's father may also have been Francis making them siblings
I cannot see a birth for John but there is a birth for Esther on Jul 6 1866
LINKThis would mean the parents were Francis WALLACE & Margaret MCULLOUGH
They married on Mar 20 1851
The informant on the civil death certificate of Margaret McCURLEY was a Grace McCULLOUGH
There is nothing proven amongst this information but I would hold as relevant until ruled out
It definitely looks as if the beneficiaries of the will were brothers-in-law
