Pascoe of Gisborne New Zealand

Looking for info on my father in law, born Edward John Pascoe born Gisborne, 1905 died Liverpool UK 1965.
I have info about him between 1946-65, but no info before then. He was a greaser on ships mainly between NZ and UK. In 1946 he was recorded as single, but that doesn't preclude another illegitimate child. Any one any ideas thanks
