I don't know if you will pick this up.
Julia Maddox was the grandaughter of my 3xgt grandparents, Wm Headon and Julia Darcy, both from Ireland. She married Hugh Boyd at the reg office, Melb in 1877. Her mother was their eldest daughter Bridget Headon who married Frederick Maddox/Maddock(s)/Maddix-lots of variations- in Bendigo, 1852. Bridget was born in Chatham, Kent, England in about 1834. Think Wm Headon was a soldier with the 50th Foot regiment, West Kent and came out with the garrison to guard convicts in about 1834/5-still investigating.
