There is a wealth of information on John Man and his family in the book cited below, including names of godparents for children, locations of baptism, etc.
All information on the Man family comes from a book that purportedly transcribes journals made by John Man, Edward Man and other Man family members, from the time period:
Samuel Hambleton Needles, Record of the Man, Needles (Nedels), and Hambleton Families 1495-1876 (by subscription, self-published, Philadelphia 1876). Available free through Google Books at https://play.google.com/books/reader&printsec=frontcover&output=reader&id=hOM1AAAAMAAJ&pg=GBS.PA1
