I cannot get anywhere with this man. His birth as recorded does not exist in Scotland, nor census records. And I cannot connect him to Kelso
1883 Born Scotland (from RIC register) But Scotland's people only gives "Hugh Cameron's" rather than other way round, and those being in 1877 and 1879 in Glasgow. And there are no "Cameron Campbell". I can only assume that either it is not his birth name, or he is one of those two men just mentioned.
