Karen,
I think that I might be correct in saying that the " Wattleworth " family may have come from Peel, I.O.M.
I do know that there is a "Wattleworth Farm" just outside Peel and on the Peel Road there is a very large house, a BEAUTIFUL one, which is called the BallaWattleWorth Nursing Home, I worked there in 1993.
This is now in the process of closing down, due to the present owner being ill.
I do not know if this will help you or not.
Why not contact the Isle of Man Family History Library in Peel?
They maybe able to help you further.
Good Luck
Carol.
