The 13th child of George & Sarah Webster, exact date of birth uncertain, was born in Lebanon. Her father dying in 1721 means she never knew him. She married Joseph Cobb in 1763, at age 42, according to Bolton, CT. town records. Lebanon town records show that in 1741, Sisters Zerviah & Mary Webster, of Lebanon, released to their brother Samuel the land in Lebanon which had belonged to their late father, George Webster of Lebanon. In 1767, Joseph Webster, of Bolton, had land in Bolton deeded to him by Ralph Cox and his sister, Zurviah Cobb. Nothing else is known. The End.
