Coming late to this so you are probably sorted. I was on Ancestry but came off a while back, but hope to resume shortly. My full info is on that site so I can only give you a little from memory. My ancestors were Shannock fishermen back to 1630, surname Grice. My great grandfather, Robert Henry `King Kong` Grice and his younger brother ` Chicken` Grice were on a lugger in Grimsby, around 1870-ish. If my memory serves me correctly, most of the crew were also from Sheringham given their surnames. The census I think gives the vessel name and the roles of each crew member ( 7 I think ). Anyway, if you think this will help let me know and I`ll get the kosher info from Ancestry.
