Hi Cam,
The Maria Callaby you are relating to in your message, is Richard Callaby's Sister, born in Docking, Norfolk on 28 Mar 1826. Her parents were William Callaby & Elizabeth Hart. She arrived in NSW on 15 Mar 1851 per the "Garland". I am descended from Richard Callaby & Ann Irwin/Irving through their dau Maria who married Peter Charles McBow.

Hope this has been a help. Feel free to contact me.
