I meant to add too in terms of Aileen Marrying again, I've a British Army man who married a Cork woman in 1903, they had 3 children in South Africa between 1904 and 1907/1908, his wife died in 1908 so he sent the 3 kids back to Cork to their grandparents, he finished in the Army in 1919, but in 1915 remarried and lived in London with his second wife and her daughter, his own 3 kids stayed in Cork, so I wouldn't rule out Aileen marrying again either and just leaving her kids where they were.... Unfortunately in those times kids weren't told a whole lot about what was going on..
