Not sure how this information is assembled, but Mr. Mercer didn't create this page.
Wonder who the listed associates/family members are, and why they aren't publicly looking for Mr. Mercer????
I googled myself before and found one of these pages for me. It pulls info from search engines, public records, etc and compiles it to make a profile that you can "claim" and make an account and edit information that is incorrect or out of date. A LOT of the info they have on my page, both my roommates pages and various other family members I searched on there are WAY incorrect. Like, it says my brother is married and I know for a fact he isn't and has never been. It also says I am a registered republican and I have never registered to vote (and sure as heck wouldn't have registered as a repub lol). I could go on about all the incorrect info but it'd take ages. It's a place that would be ok to get an idea of a persons DOB, possible relatives, locations seem correct except in a few instances I found with people I know where the people have definitely moved and their most recent address on there is something from 15 years ago.
