And I have now proven that Thomas Delves 1691 who married Elizabeth Bridger is father to William in Benenden 1716, as well as two other siblings (see IGI) and then few siblings in Waldron which then ties in all my trees together. (Thomas, David, John, Elizabeth....) So it all fits. The oxford alummni and susses society of archealogy mentions that William 1716 matriculated in oxford , BA and then MA, and mentions his father Thomas of Benenden.
Great to have tied in all the branches together
