In a 25 Apr 2009 email, Elizbeth (Betsy) Dean Vanasse provided a link to the web site of the Potter County (Pennsylvania) Historical Society, which includes transcriptions of several Family Bibles.

One of those Family Bibles belonged to John Dean and his wife Sarah Blake. It includes birth dates for their children, including those born in Townsend Township, Norfolk County.
You can link to the transcription of the Dean Family Bible by clicking here.

What follows is our 26 Apr 2009 cut and paste of that transcription. We recommend comparing it against the Potter County Historical Society's transcription to catch any updates to their posting.
