one of the team's stars, archibald mcmahon, was her great-great-uncle.r of the card for years. she keeps it squirreled away in a candy box and takes it with her when she moves into flo's house in great barrington, massachusetts. but neither she nor her daughter knows which guy in the picture is uncle archie. what'd she tell you about it? >> she said, "put this in with your genealogy." >> in the spring of 2015, flo's been digging into their family background at the free genealogy program at the local senior center. so do you bring the card to show the class? >> i brought the card to the senior center. he said, "oh, my god. it's perfect." >> "he" is volunteer steve strommer, who runs the class. >> my interest in genealogy started a long time ago. but it's taken on a life of its own, and it's pretty much an obsession. we couldn't find too much on archibald. but that was a very old card. and she said, "how much is this?" and i said, "well, i'll see if i can find out." >> are you thinking to yourself, "i really have something valuable here"? >> yes, i did. >>
