I am trying to resolve the ancestry of my grandmother, Frances St Barbe Moore. She was known as Peggy. I believe she may fall under your family tree.
I have very little knowledge about her.
She was born in Ireland (not very helpful: I don't even know whether North or South!), and must have emigrated with her parents to Australia. All I have established is that, during the first world war, she became a nurse and in August 1917, she embarked on a warship with other nurses, and presumably went to Egypt where my grandfather met her in December.
According to the embarkation records, her mother was Mrs F Moore, "Granville", McArron Parade, Essendon, Victoria. As no mention is made of a father, I presume he was already dead, which seems to rule out Robert, also from Essendon. But could she be the daughter of Samuel? Darraweit Guim appears to be less than 40 miles from Essendon.
Another possible clue is that Robert's wife was Margaret and my grandmother's nickname was Peggy, which I believe is an abbreviation of Margaret.
