I have just started trying to find information for my mother's family and am working on an inquiry. Her mother (Margaret Ransom) married Robert McLean, probably in Owen Sound. I have my grandfather, Robert's death date (Sault Ste Marie, Ontario in 1964, from an obituary, but am waiting (and hoping) for his death certificate to be sent to me. Since my mother and I are in the USA I am not sure if that will be a problem. My mother believes he was 81 when he died, which would place his birth in 1883.
When I saw the dates for your Robert McLean I wondered about the remote possbility that he might be a grandson?
