If they aren't "google-able" as handicappers or sports advisors, they really can't be all that popular. Most handicappers are search engine fiends, doing every bit they can do get on the matrix, and these three individuals don't match any search (along with handicappers). However, I don't use handicappers' services nor have any use for them, in general, so others may have more pertinent information.
I don't know what city they are in, either. There IS a Barry Wright listed on whitepages.com for Vegas, but the other names are too common to stand out among other.
Funny you should mention Chris Barnes, however. There is a very good bowler by that name who had the dubious distinction of being the first man to lose to a woman, Kelly Kulick, in the final of a major men's tournament, a PBA event called the Tournament of Champions. It happened right here at one of my hangouts for tequila, the Red Rock Lanes.
