Obadiah Sawtell, Jr. was born in Groton, Massachusetts on May 18, 1701 and married Rachel Parker in Groton on November 16, 1721. He was killed by Indians in Charlestown, New Hampshire (Fort #4) on June 17, 1749. Obadiah and Rachel had 6 children:

	Simon Sawtell
	Lois Sawtell
	Esther Sawtell
	Nathaniel Sawtell
	Rachel Sawtell
	Solomon Sawtell

Obadiah was also known as Ensign Obadiah Sawtell because he was the head of a garrison house, and the rank of ensign was always given to the garrison house commanders.

At some point in time (the exact date is unknown) when Fort #4 was in danger during the Cape Breton War, a band of militia commanded by Robert Dinsmoor (1692-1751) came to the fort's assistance from Windham, NH. Little did Robert Dinsmoor and Simon Sartwell (Obidiah Jr's. son) dream that some one hundred plus years later in 1850, two of their great-grandchildren, namely Helen Milne Dinsmore and William Lovell Sartwelle, would meet in Texas and be married.

It is assumed that Obadiah Jr. was buried in Charlestown's first cemetery. All of the graves were later moved to Forest Hills Cemetery in Charlestown, but no headstones. Many of the Sartwells were buried in Forest Hills in the lower part of the southeast quadrant including his wife, Rachel.
