I did wonder if the Samuel Clarke, that died in 1919 at Trillick Street, Belfast, could be "our" Samuel.....I notice that he was given as married, which our Samuel would presumably still be, even though he tried to kill Susanna, and she was in Scotland......I assume that divorce was virtually unheard of back then, although there was a rumour in the family that when he came out of jail, he re-married, and had another family, but I have no evidence of this.....how would I find out, if indeed it is possible at all, who this Samuel was married too ?
