"7. Sergt. Thomas1 Spencer … married first, Ann Derifield, … The will of Barnabas Derifield of Braintree, Mass., proved in l680, gave all his estate to his kinsman Samuel Spencer, who was to pay to his brothers Obadiah and Thomas Spencer 40s. each. Since these were the three sons of Sergt. Thomas by his unidentified first wife, and since the will of Sergt. Thomas cuts off his son Samuel with little, 'he having received a good portion from his Uncle,' it follows that the first wife was sister of Barnabas Derifield."
