Head of River also comes to mind. But the origin of the Tuckahoe River is nowhere near there. I guess they meant this was as far upstream as boats would go?

Yep, head of navigation like Mays Landing.

There must be a number of other body parts used to describe topography.... arm, knee, foot, ankle, heel, hand, elbow, gut, throat, eye... mouth (like Boca Raton) and no doubt others.

Many, many deeds reference the "Head" of some swamp, millpond, or stream. Head of Shourd's Mill, Head of Great Swamp, Head of Bull Creek, Head of Tulpehocking Swamp, Head of Dudley Hole, and Head of Swago Swamp, are just a few of the references I have come across.

A little late responding. I agree with Oriental. Here is one example of many.
