States: Pennsylvania: Bucks
If you are looking for family, try looking around for a book titled "Early Friends Families of Upper Bucks" by C.V. Roberts. A lot of the Quaker families and some non-Quaker families in the Quakertown area of Bucks County migrated along a chain of meetings. Many of these families are included in this book.
Because of the way Quaker meetings are arranged, you should be able to read the Men's Minutes and the Membership Dockets and follow your people around. Many of these are on microfilm and available from the LDS. I don't know if Richland MM (Quakertown) is, but the others should be. Most of the Richland families are in Robert's work.
