Anyone know any Canfields?

Hi

I've made very good progress on my family tree, but I'm struggling to find out much about my 2nd great-grandfather John Canfield (b c1825, St Pancras; d after 1891).
He didn't marry my 2nd great grandmother Sarah Douglass, but his name appears on their daughter Alice's birth certificate. John was an engineer/engine fitter, and he appears in the 1841,1881 and 1891 censuses, living in Lambeth, but not in the 1851/61/71 censuses.

One suggestion is that he may have been at sea operating/fixing engines during at least some of these periods. Does anyone have any idea where I could pursue this somewhat vague lead?

Or is there anyone with Canfields in their family tree who could offer any information?

Thanks for any help!
