Manning/Petley families Downe Kent

Is anyone out there researching the Petley Family? I have an Agnes,daughter & co-heir of John Petley of the reign of Henry VIII,( she married John Manning of Downe Kent of the reign of Henry VIII,) and Christina daughter of Thomas Philipott/ Philpott. The Petley lineage seems to extend back several generations. But I am not sure if the list I have is correct.
