Elaine,
I spasmodically play about with my genealogy and happened to come across your mesage from July 2003. I don't know what info you have re the Callander family. My grandfather's stepbrother ** was Arthur Callander born in Hamilton Vic in 1854 and married Caroline Morley on 5th July 1877 at Whittlesea, Vic. Please let me know what info you have or want and if I can be of assistance I will gladly help out.
regards, Brian Callander
** It seems there were a few different fathers to the Callander children born to Harriet Eliza Callander back in the 1850's - 1860's.
