Lancaster County, Pennsylvania/church records

I was told that my g.g.g.g.grandfather was William Neely, born about 1710 in Lancaster, Pennsylvania. He married Eleanor Carrington. I am trying to find out what his parents names were. If anyone has any information please reach me at raymond-murray@att.net. I realize this is an earlier date than the actual settling of Lancaster. I would like to know where his parents came from. Thank you for any information you may have access to. I think his middle name might have been David.
