I’m blatantly stealing this from the comment section.
There are various online tools that give frequencies of names in, particular countries. Two are https://uknames.gbgplc.com (UK names) and http://howmanyofme.com (US names). Given that stories need names, these look like a fun resource.
A game I’ve been playing with both is attempting to come up with plausible sounding names that are actually unique.
For example Jason Harpman. I think that sounds innocuous (apologies to any actual people called “Harpman”) and not made-up but both tools indicate that the name is unique. The trick is to pick a surname that uses syllables that occur in English/Anglo names and/or are one-syllable common words in English. Obviously ‘man’ is a plausible end syllable for an English-sounding name, as is ‘smith’. So something like “Helen Oaksmith” might work. (Again – apologies to any actual people called ‘Oaksmith’).
Some possible end syllables (some nonsense, some words, some stolen from place names):
(you may need to play with an inital consonant to make it work)
Start syllables – short English words. You should get some actual names as well as fake names when you pair them up:
