You would have to search for where the records of the Duchess of Marlborough's estate are.
Try searching on TNA, or even a Google search.
(If you put "Duchess of Marlborough" estate archives into Google you will get some information. You need the inverted commas around "Duchess of Marlborough".)
Thanks for this advice. I presume the land TR farmed was that of Wimbledon Manor House completed by Duchess of Marlborough. Should I include that in my search terms?
No, I wouldn't make it too specific. Sometimes less is better on search engines.
Perhaps do a separate search for "Wimbledon Manor House".
Scrub that - I just tried it, and you don't get any hits on TNA Discovery page.
Just to say about apprentices and the guilds.
Apprenticeships were not always in the company of the occupation they followed.
I spent years looking for an ancestor who was a dyer, in the Dyers' Company records, only to find him later, when many more records came on-line, in the Drapers' company.
I also have London lightermen and watermen who worked on the river, not in the Lightermen and Watermen company, but again in the Drapers' Company.
This is because the masters they took their apprenticeships with were members of the Drapers' Company.
Just something to be aware of if you're looking for apprenticeship records.
