My great aunt was a Margaret Stuart and she was born in 1899 in Glengarry and died this year (!) in Vancouver. Her father was Kenneth Stuart and he was married to Flora (possible middle name of Margaret) McDonald (MacDonald, MacDonell) from Glengarry and they had 6 children together before Flora died young in 1904 of Bright's Disease and was buried in Wiliamstown as Mrs. Kenneth Stewart (mis-spelled). Some time after Flora's death, Kenneth and the children moved to Mannville, Alberta. I do not have really any information on either the Stuart family (other than from Kenneth onwards) or Flora's family although it seems that her family were long-time Glengarrians (Alexandria I think) and that Flora was born RC and had to leave the church when she married Kenneth. I do not know if there is a connection here but given that your lady is a Margaret and mine is too (albeit born a couple of generations later), and given the Scottish naming practices, I wondered if there was a connection. The other childrens' names were Marion (my grandmother), Angus, Donalda, Albert Kenneth (AK), and Campbell. Thanks for any information that this might inspire!
