Marjorie was born on 23 April 1801, baptized on 8 May 1801 at Lochwinnoch. Some records show the spelling Marjory rather than Marjorie. She married Robert Smith in 1820. She passed away after the 1871 census, exact date and place unknown.
 There is a Find A Grave memorial in the same cemetery as the one for her father, Robert. The memorial, however, has different dates - more research needs to be done
