Hi Shadowhunter
I replied to you some time ago and don't know if you got my message.
Alexander Jamieson was the son of William Jamieson and Jane Key they came from Londonderry, William was a policeman.
Alexander was the sibling of Catherine and George-George married Sarah Bullock in Glasgow in 1915, Catherine married an Englishman named William Henry Edwards in Londonderry in 1890 who like her father was a harbour constable.
Those Jamiesons are buried at Altnaglevin cemetery in Londonderry, if you look at the 1912 covenant under Edwards and bonds street, they are Catherines family she died in 1935 so therefore they most definitately protestant.
I am the gt grandson of Martha Edwards 1907-1980 niece of Alexander Jamieson, my grandad was born at Bonds Street in 1930.
