Searching for an OSINT tool capable of searching for real names

[greyghost_]

Is there an OSINT tool anyone would recommend that is capable of searching for someone by their real name? I'm aware of ones that can search by username, e-mail, etc, but the info I have on a person I'm looking for is their birth name, date of birth and last known location.

I'm open to testing any tools recommended, but I wish to do the hard work on my own (for both training and confidential reasons). I just need a point in the right direction.

Thanks.
