Feminine words for occupations...

English is a weird language. There are feminine words for some occupations, though they're so archaic that they are mainly used for surnames now.

The ones I can come up with easily are:

webster -- weaver
baxter -- baker
brewster -- brewer
spinster -- spinner

Are there others?

ETA: I was thinking about words with the -ster construction, though words with the -ess construction are equally valid.
