Thank you for your response - we have quite a lot of info on Edwards father, John Adam. His full service record was available from the National Archives. We know he had a brother Clark Adam who was commander of a ship called the Indus, he was lost at sea. The only other sibling we know of is Catherine (gggrandmother). We know that Edward spent time off the West Coast of Africa and had some involvement in the School of Tropical Disease in Liverpool, as well as being a GP. We have his second marriage and two children in Liverpool but no record of his first marriage. Whilst he was born in County Down his father was a Dubliner who's occupation took him all around the Irish coastline - so - it would be wonderful if you did come across anything new.
