I have research that indicates the following: Margaret Macpherson married John Berrien. They had one son. John Berrien married again after her death. Mary Macpherson 1st married 'Mr.' Prior. Second married William Berrien. She may have had only one child, a daughter, from her first marriage and two children from her second marriage. John Berrien and William Berrien are brothers, both born at Rocky Hill, NJ.
