My mom's first cousin took a photo of a Janet and Robert Menzies grave stone and put it in her Menzies genealogy research. To my knowledge, this is not the Robert Menzies that is our ancestor. FYI, the gravestone data is this:
Janet W. Menzies born March 24, 1857, died October 6, 1901.
Robert Menzies born May 13, 1857 and died October 10, 1933.
