I am also researching Scallys in Kilbeggan, but at least a generation earlier than Anthony's family of interest. My GG Grandfather, Patrick Scally, was born in Kilbeggan around 1835 and arrived in Queensland, Australia, on the 'Sabrina' in Nov 1855. His parents were Patrick Scally and Jane McDermott. Griffiths indicates that both these families may have farmed just over the border in Offaly but that is not confirmed. However, I do not know the name of any of Patrick's siblings, so I cannot point to a link to George Scally or his family, or any of the other families mentioned in earlier posts.
It may not be much of a guide, but the names of Patrick's children were: Bernard, Jane, Hugh, Michael, Catherine, Mary Rose, Johanna, Ellen, Patrick, Cecelia, Hannorah, Margaret. The Scallys/Skellys farmed near Toowoomba, then Crows Nest and Gowrie Creek which are all in the same general area.
Curiously, my Patrick had a grandson, another Fr Joseph Skelly (1899-1970), a priest of the Toowoomba diocese who would have been a similar age to the Fr Joe in the photo. (The family name changed from Scally to Skelly within 20 years of their arrival in Queensland.)
And if there are a few redheads in Anthony's photo - and it looks suspiciously like there are! - then the chances of a link grow even stronger.
