Johann Michael Pultz of New York

Has anyone finally found out where Johann Michael Pultz (b. 1711?) came from in Germany? How about his wife, Anna Barbara Guckenheim (no b. date)? They settled in Rhinebeck in 1740. Does anyone know the whereabouts of the family Bible his birthdate is supposed to have come from? It lists all his children with their zodiac signs next to their birthdates.

Does anyone know who owns the Pultz house in Rhinebeck today --the one built in the late 1700s, which descended through Pultz and then Ackert until the late 1970s? It's on the Wurtemburg Rd. near St. Paul's Lutheran.

Any leads at all would be appreciated.
