My Puffenberger information is still sketchy but I guess that your Julia P is probably a niece of my Elizabeth Jane P because of the 16 year gap in birthdates.
Family research (undocumented to date) shows that the original Puffenberger may have been George Pfaffenberger from Vemet near Kaisers-Lautern, Germany in 1733. He and his wife had 4 children at the time.
The 1850 census of Berks County, PA (really Dauphin County in 1850) showed Puffinbergers had settled in an old German settlement at Tuopehocken near Reading, PA.
I am still looking for information.
