I may be able to help you - I know of an Algama and I think they are all connected to the family in Kelaniya. The family I know is Harold Algama and he had 2 sons. Mrs Algama (Snr) is still alive as far as I know. Harold passed away some years back. He may be a brother to D.W. Let me know if this is of help to you or you already know this informtion. Best Wishes with your search.
