The Bonham family is huge, because Hezekiah Bonham married three times. This is why I have not gone further to the fourth generation. And as you will see, the tree is incomplete; several members of the second and third generations have not yet been researched by me, especially the families of Hannah Bonham & Job Emmons and Zedekiah Bonham & Prudence Heath.

One of the distinctive things about this family is the naming pattern—very biblical.

Hezekiah Bonham, born 1667 to Nicholas Bonham and Hannah Fuller of Barnstable, Mass., moved to Maidenhead Township when it was still a part of Hunterdon County. Some of his descendants settled in Kingwood Township, others in Clinton Township, others in Amwell Township. Hezekiah died in Maidenhead in 1739 at the age of 71.

For the ancestry and descendants of Hezekiah Bonham, see Olive Barrack Rowland, An Ancestral Chart & Handbook; Genealogical Notes on Sutton and Rittenhouse Families of Hunterdon County, NJ. Richmond, VA, 1935, Chart IV, et seq.
