Richards, James Jr. and Dorothy Packard, int. Dec. 22, 1776.
Because this marriage occurs just 3 months after her father Jacob's death in Feb. 1777, this looks like it could be her mother, the widow Dorothy Packard, remarrying. However, it is easily determined to be the daughter since James and Dorothy Richards of Newton had children born in 1779, 1782, 1785, 1789, 1793, 1796. Clearly this is the daughter b. 1754, and not the widow b. 1721!
