Here's some quick info. If you want to stick to the strict DA period which four to five hundred years earlier than the stats used by Fief, you're going to see different numbers
During the Anglo-Saxon period, England has a total pop of 1.5 to 2.5 million. That's not a lot of people. That's less than Chicago in 1920.
A small village, of which there are many scattered around the island, might consist of as few as a handful of households.
Urban centers like Oxford and Wallingford might have one to two thousand, but that would fluctuate during market times and times of strife.
Mid size areas like Leicester might have around 500 people. But, it would still be serviced by several churches. Including one just got the thegn and his retinue.
If a one church town is a requirement, I'd probably go with a wic of 50 people or so.
Maybe even one that's serviced by a travelling priest.
All that being said, it's your game so don't feel constrained by history. Make it what you need to be plausible for your group.
