I'm attempting to find information on John Brunner (1791-1867) who is buried at Hill Church in Berks County. His stone states that his parents were Frederick Brunner and Mary. I'd like to know more about these parents.

The stone also asserts that he married a Sarah Koch. I don't know anything more about her. I'd like to know her parents and where she is even buried; it's NOT next to John at Hill Church.

I'd appreciate any help on these questions.
