I am John Thomas Cojeens Great great Grandson. He Had a son William (Brother of John, Eleanor and Emily -- it was a big family so I dont know them all). William also worked in the same shipping line...(One of the Ships that JT Thomas worked on was the Monas Isle of Douglas). I have always been told it was the IOMSPC which they were involved with/partners in.
William married Jane Dolman moved to Liverpool/Everton and reared a large family there (Jane -my grandmother, Edie, Kitty, Mona, May, John and others)
Jane married a John Bulger(My Grandfather!)
I'm sure I could supply more info if I was to ask my mother!
