The Baldwin Historical Society has genealogy info on many long time Baldwin families.  Some family data is quite extensive, others is just bits and pieces,  but the data may help someone to find a missing link in their family history.  The families with more extensive info are:

Black, Brown, Burnell, Howard, Libby, Noble, Jewell, Sanborn, Usher, Riley (Wrilea), Murch, and Chadbourne.
