I am wondering if you found out the answer to your question about a will in Hunterdon, NJ for your John DRAKE. I have DRAKE ancestors in direct lineage. The marriage to Mary MOKE struck me as interesting because I was reviewing the early Mason marriage records and just read about a DYE who posted a marriage bond deposition, or whatever, that stated that the particular Mary MOKE was overage and was a resident of his house.
I keep tripping over the DYE family in my JOHNSON and DRAKE research.
Have you tried the New Jersey State Archives online digitals? They may have something of interest. I doubt that your John would have a will ther.
YOu may be interested to know that Cornelius DRAKE had a son named John b. in N.J. in 1782 and his brother Abraham also had a son named John c 1779. Both of these boys were the cousins of Dr. Daniel DRAKE and died young and before marriage when he became ill at college studying medicine. I conclude the son of Abraham was the boy from the following taken from the memories of Dr. Daniel DRAKE. the son of Abraham was stated to be 6 to 7 years older than Dr. Daniel Drake who ws born in 1785.
DEATH: Mays Lick Cemetery tombstone reading says "In memory of John Drake who departed this life the 7th day of Aug. 1800; aged 21 years, 6 months and 10 days"
We have no proven places of birth for Cornelius's children but they did have records in the church at Scotch Plains.
