I descend from two separate and unrelated Clark families. I also married a Clark. It has become one of my favorite surnames to research. So much so that I wrote articles about my two Clark families. So the best sources on these families is me.
1. Abraham Clark was born ca. 1650 and died at Durham, New Hampshire 18 July 1694 (killed by Native Americans). He married about 1679, Deliverance (---), born about 1658 and died after 1706, the possible daughter of Charles and Rebecca (Smith) Adams. She married secondly about 1697 Nathaniel Lamos, born about 1641 at Ipswich, Massachusetts and died before 1721, son of Edward Lamos. Abraham was a Quaker. He and Deliverance had seven children: Abraham, Sarah, Deliverance, James, Mary, Hannah, and Eli. Deliverance had two more children by Nathaniel Lamos: Elizabeth and Nathaniel.
2. Hannah Clark was born about 1692 at Durham and died there about 1740. She married there 23 December 1718, John Runnels born about 1684 at Durham and died there August 1756, son of Job and Sarah (Crawford) Runnels/Renolds. John married secondly at Durham about 1742, Hannah Knight born about 1720 and died after 1769. Hannah (Knight) Runnels married secondly Hudson Peavey. John and Hannah (Clark) Runnels had seven children: Abraham, John, William, Elizabeth, Joseph, Sarah, and Hannah. John had four more children by Hannah Knight.
