"Born Alice Carpenter, the daughter of Alexander Carpenter of Wrington, Somerset and Leiden, Holland, she married Edward Southworth at Leiden (MD 10:1). After the death of Southworth, she sailed to Plymouth on the Anne in 1623, and shortly after arrival married Gov. William Bradford as his second wife. She had four sisters associated with Plymouth Colony, Juliana, Priscilla, Agnes, and Mary (Mary Lovering Holman, The Scott Genealogy [Boston, 1919]). All the sisters eventually came to Plymouth except Agnes, who married Samuel Fuller, but died before he sailed on the 1620 Mayflower. Alice's two sons by her first marriage, Constant and Thomas Southworth, came to Plymouth after her. Her sister Priscilla's husband, William Wright, mentioned in his will his "brother Will Bradford," who had also been mentioned in the will of Samuel Fuller, her sister Agnes's widower, (MD 1:200, 24)."
