PECK Theophilus Peck, Jr., and Rebecca Knapp were married on July 6, 1753.
This is from the Greenwich, CT: Vital Records, 1670–1847
The town of Greenwich, Connecticut was created by an act of the General Assembly passed in 1665. These vital records of the town were abstracted by Spencer P. Mead in 1913. Mr. Mead was born in 1863 and was the author of Ye Historie of Greenwich (1911) and History and Genealogy of the Mead Family (1901), as well as several additional typescripts containing various records of Greenwich. These records begin in 1670 and end at 1847.

Bingo. It's correct. You can read about it free in this online book http://books.google.com/books?id=gdULAAAAYAAJ&vq=Knapp+David&am...
I read it on page 670 but the pagination is off. It lists David and Rachel's children. They had at least 4 and it says explicitly that Rebecca was their daughter and married Theophilus Peck.
