Cynthia Powell, who married Russell Lathrop (Carl's G2-grandparents), descends from two different Mayflower Passengers - William Bradford and Richard Warren.
William Bradford was a passenger on the Mayflower and a signer of the Mayflower Compact. He was one of the founders of Plymouth Colony, and was elected the second governor in 1622. He was re-elected every year until his death in 1657. He began writing the history of Plymouth Colony in 1630, which was published for a time as History of Plymouth Plantation (the free version available in Google Books), and is now published as Of Plymouth Plantation. It is considered the most complete authority of the early years of the Pilgrims and the Colony.
There is much literature and many sites that provide details of his life and achievements. One such from the History Channel is http://www.history.com/topics/william-bradford.
