Hi Jenny
I'd certainly be interested in the wedding photo of Edna (Lillian) Marsden. As you may know, she was married twice, to Eugene Robert DuBois and Frederick Goulden Francisco. As both my maternal grandparents had died well before I was born, I wouldn't be able to personally recognise my grandmother, but may be able to locate a photo from elsewhere for comparison.
Re the Spargo family, I was in Adelaide recently and went to West Terrace cemetery looking for headstones on the Marsden side and came across a broken headstone for a Mary and George Spargo. Mary died on 21 Feb 1897, aged 41; George died on 30 November 1933, aged 79. I can't place them in my tree, but they may be relevant to you.
I hope this is useful. My main tree is William Munday. My email address is
