A Bronx father and son who had once been complete strangers celebrated their second Father's Day on Sunday thanks to the help of a social networking site.

Terrell Starr, 32, says he decided to type his dad's name into the Facebook search box three years ago and sent 10 messages to 10 different people with the name Chris Truesdale. He says only one responded immediately and that they've been inseparable ever since.

Truesdale says he wishes he could have been in his son's life sooner, but didn't even know he had a child until the day he got the Facebook message.
