Further to my last message - I think I have found the WARBURTON family.  Letitia May EVANS, B. abt. 1860, N.S.W., married 1887 N.S.W. to Charles WARBURTON, born 1857 N.S.W., child Esther Elizabeth Warburton, born 1888 N.S.W.
I have them in Caulfield in 1903 El.rolls:  Charles(Labourer) & Letitia.
 1909 living in Lilydale, Mernda, Charles, farmer in Gruyere, with daughterEsther; 1914 in Lilydale, with Alfred Charles W., Orchardist, Charles, Letitia and Julia; 1924  same family plus Mary Hilda W., Teacher at Convent of Mercy, Lilydale; 1931, Lilydale, Alfred Ch., Charles, Letitia and Eva Johanna (Wandin North).  Do these people ring any bells?  Ruth
