According to the death certificate of Martha Jane Sullenberger Miller, sister to Benjamin, their parents were Isaac Sullenberger and Christiana Pepperly (?) The death cert is a bit difficult to read.Isaac is buried at Mt. Bethel Cemetery in Columbia dates 12 March 1803 - 1 January 1889.Haven't found much information on Isaac or beyond.
Pepperly was not a very common name in Lancaster.Thinking might have been Peffley??Kepperly??
I would really like to find a marriage record but haven't had much success.Slowly going through a list of Strasburg area churches.
The only possibilities to Christiana's relations I have seen are:
Andrew Pepperley 1800 Lancaster PA - Strasburg1755-1774 1 male under 10, 1 male 16-26 1 male 26-45 2 females under 10,1 female 16-26
Andrew Kepler 1810 Lancaster Strasburg - 1 male 10-15, 1 male 45+, 2 females 10-15, 2 females 16-25, 1 female 45+
In 1830 Isaac is listed on the same sheet as a Jacob Sillenberger age 30-40, 1 male under 5, 1 5-10, 2 females under 5, 1 female 20-30 and a Sharlet ?Pepper? with 2 adult males
