HI Brian,
thanks for that, i asked the question because a relative of the crennells in whom i am trying to piece together with my late dad, got in touch and said william crennell lived in onchan and they have a photo of teddy crennell [ mungie/edward james ] on his boat Iona, he still was a fisherman in early 1960, as i get told of him carrying live lobsters in his pocket trying to sell, so i wondered where this boat travelled to, and maybe thats how catherine cain just vanished,
