Family moved to New Marlborough, Ulster County NY circa 1768.

July 1775 Job, his brother Ebenezer, and Job’s sons Matthew, Noah, and Samuel signed the Marlborough Articles of Association. On 13 Aug 1777 Job was entered as an exempt in Capt. Jacob Wood’s Company, Fourth Regiment, New York militia. This company was centered
around northeast Marlborough, near Newburgh {12, 21:110}. Exempts were
composed of older or infirm men and were assigned mainly to guard duty.

Under the heading "Residents from 1779 to 1788" he appears as follows: "Nathaniel
Kelsey and Job St. John had large holdings north of Milton." This Milton is a suburb
of Marlborough {26}.

On 26 November 1785 he notified the Marlborough town clerk that he was holding a
stray red heifer of two years old and upward {21:204}. In 1788 he and four of his
sons were listed for road work. His assessment was six days work, which reflects a
higher than average property standing in the town. {20b} He does not appear on a
similar list of 1799, though his brother Ebenezer does.

No wills or letters of administration have been found for this couple.
