[There is no direct knowledge that Mary's surname was Gillies. Researcher Fay Dobson claims to have tracked it down on a relative's certificate. (Birth, Death or Marriage unknown). It's not known if the name is a birth name or a married name. It is generally accepted throughout the family that she was known as Mary. Therefore Mary Gillies has been accepted as a suitable name for recording purposes but doubt remains.]

[The source of the initial 'S' is unknown]
