Hello Suzie
That sounds interesting, I wonder what happened to John Davies, he must only have been about 35? Although I have John and Rebecca in my tree, I'm afraid I don't know anything about this story, sorry. However, I imagine there might have been a piece in the County Herald about this if you have access to old newspapers. This paper seems to have a lot of reports about Bagillt, and as Rebecca seemed to be living with her mother at Coetia Gwyn, Bagillt when John was at sea, there might be an obituary or something.
The only info I have about John and Rebecca is:
MARRIAGE: St Mary's, Bagillt
Jan 30 1895.
John Davies. 26 Bachelor. Mariner. Bagillt. Father John (Deceased. )
Rebecca Tattum. 26. Spinster. Bagillt. Father John. Lab.
Witnesses. Stephen Davies. and Mary Ashford Tattum.
Baptism. Sep 29 1895. Mary Edith Davies D/O John & Rebecca. Bagillt. Sailor.
Did they have 4 children: Mary, John, George and Catherine?
Sorry I can't help, but I hope someone else can.
