I am seeking information on the ancestors of John Hamlin, b. 1727, Suffolk Co, NJ; possibly married to JoAnna Royce, b. 1730, Wallingford, CT. Any military service by John, his ancestors, or descendants would also aid in my research.

I believe my line is:
John 1727
John 1759 and Nathaniel 1757
Eleanor 1790 m. 1st cousin Charles 1799
David Brooks Hamlin 1830 (Civil War; Infantry)
David Brooks Hamlin 1879
Anna Frances Hamlin 1910

I would greatly appreciate any assistance.
