(I) George Potter, the immigrant ancestor, settled early in Rhode Island. He was born in England, and died soon after 1638, it is supposed, as no further record of him has been found. His widow married Nicholas Niles. George Potter was admitted an inhabitant of the Island of Aquidneck in 1638. He and twenty-eight others signed the following compact, dated April 30, 1639: "We whose names are underwritten do acknowledge ourselves the legal subjects of his Majesty King Charles, and in his name do hereby bind ourselves into a civil body politicke, unto his laws according to matters of Justice." Nathaniel Potter, probably his brother, signed the same compact.
