Yes, that makes a lot of sense. The significant name is not Margaret, who married William Caley (or at least had seven children with him), but her sister Ann, aged 17. She was the one that married John Kelly and had seventeen children. Cranstal is the hamlet about half way along the main road from Bride village to the Point of Ayre. It includes a much-photographed thatched cottage and a cluster of farms, the last of which is on the coast. Here it is called Port, for it used to have a little jetty before coastal erosion carried that away. The Manx form is Purt, or in its mutated form, Phurt, which is the name that appears on the maps.
In 1871 Ann, now Mrs. Kelly, is at the Kimmeragh, inland on the Andreas road out of Bride, but her parents William and Elizabeth were at Ballaragh Farm House. In their Bride Miscellany the Radcliffes find that difficult to place, but definitely in Cranstal, therefore close to the Bruces. William and Elizabeth had with them their little grandson James Kelly, aged 2, Ann’s tenth child. No doubt he saw quite a lot of his big sister Sarah nearby.
Just to make Sue’s head spin a little more, William’s wife Elizabeth was also a Joughin. They were first cousins. Their son Charles married his second cousin once removed Esther Joughin. Charles and Esther’s daughter Alice married her first cousin once removed William Joughin. The last two marriages took place in Liverpool, away from disapproving relatives. By now the genes were exhausted, and William and Alice’s only son William, a promising medic, did not reach his 30th birthday.
