I'm trying to find sources for trees of old varieties of pears that were grown in SE Pa. or southern NJ in the early 1800's. Does anyone know where I can find: Brandywine, Bleekers Meadow, Bloodgood, Edward's Elizabeth, Harvard, Leech's Kingsessing, Madeline, Moyanensing, or Petre? My source is Coles 1848 American Fruit Book. Thanks. Mike Tomlinson
