I always find wills one of the biggest areas to try and find previous generations.
It wasn't only rich people who left wills. I have many wills from not very well off tenant farmers.
You may also find your ancestors mentioned in the local Manor Court rolls taken by the lord or lady of the manor.
The National Archives have a page to look up where records may be held. The Manorial Documents Register.

Then there's any number of Taxes that were raised at one time or another: Land Tax; The Hearth Tax; Muster Rolls...............

You will not find a lot of this sort of information easily accessible on-line, apart from wills, which if you're lucky will be.
It takes a lot of digging and no doubt visits to any number of depositories at Record Offices; libraries; universities (who seem to hold lots of records in their special collections libraries); private archives etc etc.
The Manorial Documents register above gives you where any pertinent records are held.
And don't forget The National Archives Discovery page itself.
https://discovery.nationalarchives.gov.uk/This covers millions of records. Try your ancestors' names.
And digging around on there often throws up things of interest, if your actual ancestors' names don't appear. For example, TNA might hold something general about the village of Dulas, but it's not until you've looked at the actual document that you can find the names mentioned in it.
I see there are 44 hits for Withiel Florey between 1600 and 1699 - at a very quick glance, a lot of them are manor court records.

You're right though Ayashi, if you have several generations with the same name, it's can be tricky to differentiate between them.
