Hi ADP,
Well found, that is interesting that George and Elizabeth had different amounts of children, maybe indicates a previous marriage. 1855 was the first year of Official Registration, and you got a whole lot more information.
On LDS, I found a birth to these parents for a James Beaumont on 1 October 1858 in Hutchesontown in Glasgow. He was born 2 months before his father died, and he died in 1858, there is a death certificate on SP for him, mother's maiden name, Marr, ties in.
