I believe this is the grave of my Great Great Grandfather, Alexander McTaggart b. 1823 Argyll, Scotland d. 1923 Gympie, Queensland. Also his daughter Mary McTaggart (McDonald) b.1853 Dalry, Argyll, Scotland d. 1926 Queensland. Alexander married Mary McInnes, thereby making the headstone correct,(Husband of Mary).
