Maggie C. Smith's mother was Mary Lue Gill. I don't have dates on her other than she married at 14 years old to Enoch wiley Smith. and that Mary died from what they called Bloody Flux back then. Mary Lue Gill was the daughter of Michael Gill born in 1850 in Ireland and Ella L. Gill born in 1866 or 67 in Ga. Ella died in Oct. or Sept. of 1939 and thats as far back as I have on that line.
