I assume you are looking for your genealogy. From your mother Marjorie Francis Rideout on back to Bradford Oliver Rideout aka Oliver Bradford Rideout is well documented but going back from there is difficult.However we do know who Bradford's grandparents were.The only Rideout to migrate to New Brunswick in this time period was Nicholas Rideout Jr. 1737-1833 and his wife Sarah Oliver 1740-1787. They had eight sons between the years 1763 and 1786 of those only four could have been Bradford's father. Which one?
Nicholas b 1763 Thomas b 1765 Oliver b 1767 Abraham b 1770
