She was the daughter of Henry Hill and Ann Hoskins. She married in 1763 to Charles Carroll and had three children named in his will and hers. She married second Ignatius Fenwick in 1780.

MARRIAGE: c1763 Charles Carroll and Mary Hill married. Unable to find marriage record. Different posts have said Feb 13 1763 and Jun 5 1768 but no sources. June 5 1768 is the date Charles Carroll of Carrollton married Mary Darnall so this is an error and mixup of two people and two separate marriages. The 1763 date is more likely to be accurate since the 1765 deed proves they were already married by then.
