The subject of trade and occuaption sources is vast. David has previously done the workshop based on the themes 'Family History' and 'One Places'. Now he has prepared one on Rural Life and agricultural trades. While there is some overlap it does use other records.
The guidance notes and the flow diagram on this web site are still relative and should help members with their ancestors trades. So if you cannot join the workshop look at these guidance sheets, they may be of help.
If all fails don't forget you can request a discussion workshop to gain help on any aspect of family history. Email firstname.lastname@example.org to request a theme for one of the discussion zoom meetings.
