William Gibbens was from a Somerset family. This is the will of a young-ish man, his unnamed father is dead, but his mother is still alive and all his brothers and sisters are as are his wife`s sisters. I am guessing that his children are small and that is why his wife is executor and his father in law an overseer. Hence the clause if neither child survives, as children of course very often did not. William's son Thomas went on to be a MP for Exeter.
