Long time since I added to this, but found Darby Donohue, Denis Bingham and Rose Barrett all. This came after talking to older relations, who recalled some cousins in Fife. It turns out Mary "Maria" Kelly ended up there, and her son Denis Bingham died in 1969 at Glenrothes, married to Catherine O'Donnell who died in 1991. I intend to find their own children and try somehow to establish contact there. Darby Donohue married in 1922 to Catherine Swan, and the certificate shows his father to be Margaret Kelly (1874-1905) who also had the twins John and Rose Barrett. I can't locate the couple afterwards, and perhaps they emigrated back to Ireland or elsewhere. Any ideas would be useful here. Rose Barrett married in 1929 (as Rose Kelly) to James Davitt. Still need to find their fate too.
My main area of interest is still Anthony Kelly's parentage. I find on Griffiths Valuation that there was a Terence Kelly in Muingmore, the same township. He married Mary Conway in 1839 and had two daughters, neither of whom appear later on the registers. Given location he could well be a relation, even the father of Anthony. But I am also considering the Kellys of Rathmorgan, who included Hugh Kelly, James Kelly, Michael Kelly and an elder man named Edward Kelly. It's not too far from Muingmore and Maria and Anthony Kelly both worked nearby in Rathill later on in time.
The other difficulty is finding Bridget Kelly's death, perhaps someone can help me here. She was known as "Aunt Biddie" to the family, and they say she died around Edinburgh, from a bowel problem, was single. She may have been 90 years old, but that seems an exaggeration. Her death date is recalled around 1956, and the only Bridget Kelly I know of is the one born in 1883. Unless "Aunt Biddie" was in reality a cousin, that is a niece of Anthony Kelly and his wife Annie Carey? If so, that unlocks Anthony's own family somewhat. But in any case I searched every certificate for Bridget Kelly and none show her with Anthony and Annie as parents. In this case, where is Bridget Kelly? Just seems to disappear off the grid.
