Mein Doppelgänger

I Googled my name last week and found a few places on church sites that had my name, a lot of items on an American football player who plays on some European NFL team in England. Then I found a guy in Germany who has a computer business. I sent him an email introducing myself and some of my family background. He wrote back and thinks we might be related somehow. His father’s family is from Yugoslavia like mine. My dad thinks a possible connection might be that my grandfather and this German guy’s great-grandfather were cousins. I’m going to keep in touch with the other me and try to work out if and/or how we might be related.
