Regards Campbells - I have a Joseph Archibald Glenlyn Campbell (son of John C & Mary) m St.Philip Neri's Church, Pettah, 14.1.1886 Lara Amelia Therese de Silva and had James Archibald Nicol Collin b. .1`0.1886. and an Angus among others. Also Archibald Campbell m Christ Church Galle Face 28.4.1881 Lilian Charlotte Swan b.3.5.1861 and had Mary Annabelle in 1883. Could be the same person?
Only one other Colin Campbell but he had a son in 1868 so could not have been born 1857
Alexander Campbell - There are several but all were having children in the 1850s or earlier. Could all be the same?
A little more information from Gay Fielding could help.
