A little earlier in the week, I held the first tutorial of the latest Introduction to One-Name Studies course. The topic of researching in the Middles Ages came up and we shared a number of links:

Medieval Genealogy – https://medievalgenealogy.org.uk (the site does give a security flag, but it is perfectly safe, I used it last night!

Medieval Soldiers Database – https://www.medievalsoldier.org/database/

Someone shared the Gascon Rolls – gasconrolls.org

There are also these projects that are worth exploring:

Henry III 1216-1272 Fine Rolls – https://frh3.org.uk

Inquisitions Post Mortems, Mapping Medieval Countryside, Properties, Places and People – https://inquisitionspostmortem.ac.uk/
This project has a wide range of information 1236-1509
The online digital edition at the link above, using the browse functions covers 1422-1432
This link https://inquisitionspostmortem.ac.uk/browse/people/a/ covers the period of 1399-1447

For these early periods, surnames were not standardised, and the following of an individual found in one record and descendants in another is unlikely. However, search for your surname and see what pops, you might also need to search for possible variants. For Butcher there is limited results, but there are plenty of BOCHER results. I have not registered Bocher as a variant, but I do gather them as I see them. When I find one Bocher and the same individual becomes Butcher, then I will likely register the variant. We will talk about variants in the tutorial for lesson 2.
