I found a website that says that the Elizabeth Rutt that Married Rev. Mordecai Andrews II was the granddaughter of John mason II, son of John Mason (A non-conformist minister and Poet).
"Revd Mordecai Andrews I (c1715-49) probably succeeded Thomas Shepherd as independent minister in Bocking (Braintree, Essex) on the latter's death in 1739. In 1743 he was brought in as a 'young man' to take over a moribund congregation in Petticoat St, London, and expanded the congregation so much that they took over bigger premises in Artillery Row.
Revd Mordecai Andrews II (1740-c1819) was christened at Bocking Independent Church (where Thomas Shepherd was minister from 1700 to 1739) on 22 August 1740, the son of Mordecai Andrews I. He became minister of the independent church in nearby Great Coggeshall, probably being the immediate successor of Henry Peyto. His wife was John Mason II's granddaughter, who was probably called Elizabeth Rutt."
