Don't have much info but might ring a bell with someone :)

Catherine McIntosh (born 1883 Hamilton Barracks Lanarkshire) Married John Aitken (born 1881 Lanarkshire) on 11th October 1907 in Glasgow. John was the son of Alexander Aitken and Mary McLellan and was a coal miner. They had 4 children Alexander (born c1908) John (born c1911) Edward Rittman and Elizabeth.
Not sure if the children where born in Scotland but think more than likely they were born in South Africa. John died in 1924 in South Africa and Catherine re-married to a William Hannay (he died 1942 South Africa)
Anyone have any connection to these names ?
Thanks
