The search for the family of 615 T/SGT Charles Otho Fitzgerald threw up many unexpected surprises. Charles was the son of Lord Charles Fitzgerald who was in turn a son of the 4th Duke of Leinster. Unsurprisingly, there is quite a bit about this family in the Victorian newspapers from the early 20th century. I've included a few articles below.
Charles was a member of the 9th Light Horse Regiment. It would appear that he suffered an injury after being kicked by a horse and subsequently transferred to the Anzac Provost Corp. Charles brother George served as a captain in the 5th Battalion.
After the war Charles married Mary Pearl Millicent McIntosh but they didn't have any children. I followed the families of several of Charles' siblings and it was through his sister Mable that I have arrived at the current generation.
Mable married Robert McCracken who also served with the 5th Battalion. Robert was an original Anzac and this story provides some interesting information about his family.
It is Mabel's grandson who I've been in contact with and will return the medal to.
Thanks to Helen M who sent the medal to me.
The returned medal tally is now 1624.
