Looking for info on gr.grandmother Ann Mackay (parents unknown) born abt 1865-68 immigrated to Canada from Isle of Lewis early 1880's. Worked at Lower Fort Garry. Married William Tyrrell (spelling?) from somewhere in Scotland, abt 1890 who changed his name to Mcdonald (before or after marriage?). They settled in Selkirk Manitoba, had 8 sons & 5 daughters. William buried somewhere in Scotland in 1936, surname used uncertain. Ann in Manitoba in 1937.Any help with Ann's family sure would be appreciated.
