How to get relevant people searches for a common word?

I'm researching the Windmill surname. I find that most of the results I come up with online and in searches in newspapers etc are related to either a windmill (eg Pitstone Windmill) or a road (eg Windmill Close) rather than a person (eg John Windmill) as there are not many people with this surname.

Does anyone on here have any good tips how I can search resources more efficiently?
