The only folks named Daniel Ennis/Ennes alive at the time are Daniel 1744 - 1838, son of William Ennes; and Daniel 1788 - 1862, his nephew and son of Joseph. The latter is too young, so it must be the former. By 1810 this Daniel, along with wife Eleanor Hornbeck, were living in Cayuga Co NY.
UPDATE: An interested reader kindly reminded me that this Daniel b 1744 is noted in Snell's History of Sussex & Warren Counties as: The earliest host remembered in the township was Daniel Ennes, son of William Ennes, who chose a location in the northwest portion of the township, near the Delaware River, where he a tavern and blacksmith-shop and opened a store. This tavern was in its day a favorite resort, and the son of Mr. Ennes [Alexander] was no less renowned for hospitality than was his father, whom he succeeded. (Snell, p. 420)
