Notes:
-Percival was a very distinguished and successful man in England. His ancestry has been traced to King Edward I of England and earlier. He lived in Kingston-Seymour, Clevedon, Portbury, and Bristol. In 1597 he was assessor in Kingston-Seymour. He appears with coat of arms in the Herald's Visitation of Somersetshire. In Bristol, he ran a large mercantile business named " Percival Lowle and Co.". He was admitted tenants of eight acres of land in Portbury, and was churchwarden there in 1613, and then baliff in 1621. He immigrated later in life, in 1639, aboard the ship "Jonathan". He arrived later than many other settlers, and did not receive any land grants in the new world, but he did purchase his own land. Upon the death of John Winthrop, he wrote a long poem, which survives. He was a learned and well educated man. He lived to be 93 years old.
