I am living in Canada and I have McPherson lines originating in Glasgow.
My grandmother is Susan McPherson and she had two sisters that I know of, Jeannie (1885) and Annie (1887). According to the 1901 census, it appears that the girls were attending St.Columba's boarding school.
Susan Clelland McPherson
b.24 Oct 1890 2:00 AM
77 Inglis Street
in the Burgh of Glasgow
They were born to John McPherson and Mary Deans West m. 29 June 1865 in High Church. Susan married Alexander Gray and emmigrated to Canada OR she emmigrated to Canada and married here. I have no records to indicate which.
That's about all I have sadly.
