John Taylor, who is supposed to have come from Wiltshire, was a resident of Tinicum Island in 1684, as a lessee under Christopher Taylor.  The name of his wife was Hannah, and their children, Elizabeth, Isaac and Jacob.  He was deceased in 1688.

His daughter Elizabeth was married 1-1-1686 to Hugh Durborow, who with the rest of her family moved to Thornbury.

Jacob Taylor acquired a good education and was engaged in teaching school in 1701, when, owing to the death of the surveyor-general, he was called to take charge of that office, and about 1706 was commissioned surveyor-general.  He was succeeded by Benj. Eastburn in 1733, and retired to live with his nephew, John Taylor, in Thornbury, where he died 3-2-1745-6.  For several years he prepared the necessary calculations for an almanac, together with verses of his own composition and other matters, which were published by Isaiah Warner, Wm Bradford and perhaps others.

Isaac Taylor, brother of Jacob, resided in Thornbury, and was deputy surveyor for Chester Co, from 1701 til his death in 1728.  He married, in 1694, Martha, dau of Philip Roman, and had children - John, Jacob, Philip, Ann and Mary.  Ann married Samuel Savage, of Coventry, an ironmaster.
