Hi JJ
I'll leave it with you to verify etc.
In the meantime, this MAY be them, the surname is hard to read though.
1841 at Werham? Common, Stoke Poges, Bucks. Richard Ag Lab 40 or 42, wife Mary 40 (both born in county), Richard 15 (not born in county) Marianne 12 (not born in county) and other children born in county. Will give the full details when and if you are ready.
So the born on the seas appears to be correct, or at least not in Bucks judging by the other census entries.
Regards
Biker
