Crazymage pretty much has it covered
1. Use real world names like Khrzyg and Blayney
2. Get a list of suffixes and add a common word
eg
~town
~ton
~thorp
~ham
~dun
_wick
~lys
add Fell (or Fel)
= Felltown, Felton, Fellthorp, Felham, Feldon, Fellwick, Fellys
add Nor
= Nortown, Norton, Northorp, Norham, Nordun, Norwick, Norlys
then place as desired
