I have a question for anybody who can answer...While researching my gr. grandpa born in Edisto Island, and lived in Charleston ,South Carolina from 1850-? this document I have said his occupation was a 12" keeper right away I thought it had something to do with the fishing industry is it possible that they actually had a position where someone was in charge of making sure the fish were at least 12"long in order to keep them? Well I can't believe I had to sign up for this sight just so I can ask somebody this question. I'll keep it and maybe use it now and then because I'm not a very skilled fisherperson..thanks
