Did not find the names you mentioned in the Fisk/Fiske gen. Samuel and Benjamin Fiske both born in early 1680's(sons of Joseph and Elizabeth) were the early Fiske's in Scituate, RI, in about 1725 or before.The book has little or no info on some of the grandchildren of Samuel and Benjamin.Perhaps you may find something on the web. Sam's info seems to have more gaps, he is the more likely of the two, to be John's father or grandfather.
Benjamin's wife was Abigail Bowen. My line thru them - file"1282574" In your search you will note a number of files that list Benjamin as son of Dr. John and Hannah (Baldwin) Fiske.That info IS INCORRECT.Their Benjamin would have been 5/6 years younger than Abigail.What gal(in her early 20's) in her right mind (in any century), would marry a 16 or 17 year old kid, who she would have only known a short time, since Dr John lived in Milford, CT, a good 100 + miles west of Rehoboth, MA, where Abigail was raised on her grandfather's farm.
Samuel and Benjamin spent at least the last half of their early years on their parents farm in Rehoboth (their farm was next to that owned by Richard Bullock -Abigail's maternal grpa).
