She was   23  and bored one night last year, so she typed her name into the   24  social networking Website Facebook just to see if anyone   25  it: Hildebrandt, 24, in South Florida. At the time, Kelly Hildebrandt, of Lubbock, Texas, was the only one matched. So she sent him a   26 . She said, “Hi. We had the same name.

She's a student at a local community college. He works in financial   36 . They plan to make their home in South Florida.
There was also some uncertainty   37  how to phrase their wedding invitations, so they decided to include their   38  names.
