I am researching my own family, which includes Pfisters (Indiana, Florida and Bavaria), Whitehursts (Indiana), Grahams/Collinses (Kansas and Arizona).
I am also researching a family only connected to mine by a historical interest, that of the Trumbulls/Gallaudets (of England, Connecticut, and New York) which includes Parrish, Caraway/Carraway, and many other family names.
My own family I have traced back quite a few generations, and the Trumbulls I have managed to track back to 1606 to Newcastle-on-Tyne, and the Gallaudets to France about the same time.
I am very willing to share any information I have with anyone who requests it!!!
