I don't know if you are still actively researching this. The Olive Stathers I am researching had a grand-daughter (his daughter married a man called Jones) who married a man called Tranter in Middlesbrough (which makes me feel we may be looking at the same person). I knew these Tranters well in my childhood.
I have only been able to trace this line forward to myself (and maybe you?) and his past remains a bit of a mystery, possibly due to his life at sea in some part.
I would be keen to exchange knowledge if you are interested?
