Dr. John van Buren of Granville - Where did the Dr. practice medicine in NS?

One guess is (modern) Karsdale... known before as Lower Granville.

Notice the use of the given name here: http://www.hhennigar.ca/getperson.php?personID=I44977&tree=1.
"John van Buren Foster" < the John Van Buren name might honor Dr. John Joseph VB... (?)
Additionally.. Dr. John's first known child (Job) is buried in the Chesly cemetery, not far from Karsdale/Lower Granville..

I'VE CHECKED the cemetery in Karsdale for clues,,, no luck

another lead would be that as his infant son Job was buried in Upper Granvile's Chesley cemetery, perhaps relatives by marriage buried there would give me clues:
Israel Fellows
The Fellows family fits this... I should examine more possibilities at http://www.rootsweb.ancestry.com/~nsannapo/cemeteries/upper_granvil...

For 17 years, Dr. John lived with a family in Berwick NS. John had deserted his wife Susan (Roop) These "17 years" were before 1850 when John had moved to Tennessee. Evidently John was infirm by then and was under his younger brother's care in Haywood County.

Berwick was then John's base of operations as a doctor. There is an account of his riding on horseback to serve his patients from that locale.
