Laura GIRARD AKA Marie Laura Alexina

This is my Grandfathers aunt and he desperately (as well as me because its been a huge challenge) to find where she ended up.
She was born in Dunham Quebec canada 21 May 1895 to Arthur Girard and E'lisa Marcille
"rumor" has it that she was disowned by the family and moved to the stated (most likely the upper eastern states).
Many in her family died of TB.
She would have been the last living direct ancestor if she had stayed as many died or came to ontario in 1918 to join up for the war in guelph.
Any help would be great
Thanks
Trish :)
