I've got a vast range - A is for accountants, ag labs, architects, attorneys; B is for bakers, bankers, bookkeepers, barristers, blacksmiths....Y is for yeoman, yeoman and yet another yeoman.
In terms of trends, I've got a good smattering of C of E clergy and, in my Yorkshire lines, shedloads of people who made their living in the wool trade: wool/worsted spinners, carders, piecers, sorters, staplers, manufacturers, traders, merchants, mill owners etc etc.
Also (in London and Birmingham lines) a surprising number of attorneys, barristers, magistrates, J.P.s and one solitary judge - I'm a barrister myself but had no idea there was any family history of it before I started.
