Re: Peabodys of Sherbrooke, QB
This may be a complete red herring, but I had a fantastic high school teacher named Lyndall Peabody, in Lennoxville, QC (just outside Sherbrooke)in the 60s. She was a Mrs Peabody and her husband was, I believe, named Gordon Peabody. He was an Anglican clergyman. I think he may be at Christ Church Cathedral in Ottawa now - I just googled him. I'm not sure whether or not he was originally from the Sherbrooke area, but it might be worth a shot.
PS: I think that Mrs Peabody died a few years ago, but I'm not certain.
