Producers from the British Broadcasting Corp. show "Who Do You Think You Are?" scouted the historic Hazen Garrison House recently as a site for future filming. Someone's family tree led the producers to the house at 8 Groveland Street, but they are not revealing the star's identity. They want to preserve the secret for fans of the show, which is entering its fifth season.
The brick English Manor-style house was built in 1724 by British merchant Richard Hazen. It is about 75 yards from the Merrimack River, where he wanted to build a trading wharf. However, nobody other than the TV show's employees know if the future TV show will feature Richard Hazen or perhaps a later owner.
