Margaret was born about 1740, the daughter of Robert Scott but her mother is unknown. The place is not known.
Her husband was James Montgomery. They were married, but the date and place have not been found. Their seven known children were William (c1765-1800), James (1766-1839), Barbara (c1768-?), Archibald (c1770-?), Margaret (c1772-?), Robert (c1774-?) and Anne (c1780-c1845).
!Notes: Margaret Hotchkiss nee Hart's will says that her grandmother was Lady Elizabeth Montgomery wife of the Lord chief Baron of Scotland.
Since Ann was indeed listed as the daughter of Sir James Montgomery, Baronet, of Stanhope,' county Peebles, but with her mother being Margaret, only daughter and heiress of Robert Scott of Killearn, county Stirling. Perhaps Margaret Hotchkiss nee Hart was mixing her up with her great Aunt Elizabeth, who married her uncle James, the son of her grandfather of the same name who unherited her grandfather’s title.
