Just found out this year I have a brother in Canada , I talking from about 1948 to 1952, all details I have are very sketchy and to make things worse I lost my mum when I was very young and she only confided in 1 person who also has died but told his son beforehand but I got no idea where to start or how to go about looking in another country apart from the UK where I am from

Well what type of info do you have, names, possible names, was he adopted?

All I have is the area off Canada that she was in, close to Montreal and that's all.. I never knew anything till about a few weeks ago and no family on her side left alive so I feel as if I against a brick wall right now
