Henry Griggs was mentioned in the 6 January 1759 will of his father John Griggs, although the will does not explicitly state the Henry was a son of John. John stated that Henry Griggs is to have £25 deducted from money due from his grandfather Henry Purkins deceased which I received as an executor of Henry Purkins. If he refuses to receive it in that form then he is to receive one shilling. The will was proved 16 January 1759.
