Eleanor Billington came with her husband and two sons, John Jr. and Francis, on the Mayflower, on which they had a cabin, an unusual privilege, the reason perhaps being that the Billingtons, who were from a high-up English family, had paid lavishly for this extra comfort. There is evidence that John had a brother, Francis, who went to John Smith's colony about the same time. The family in England spelled their name Bylington. They belonged to the Judges in the time of Henry VIII.
In 1638 Eleanor married Gregory Armstrong and their antenuptual contract is said to be the first on record in America.
