Portumna

My great-great-grandmother Margaret Whelan daughter of John Whelan (a Slater of Portumna) and his wife, Anne Kennedy, married Michael Manly the son of James Manly (a Storekeeper) and Cecelia Morris, in the Roman Catholic Chapel of Portumna on 12 January, 1865.  This young couple came to Australia later that year.

I would be grateful to know -

• Would I be able to obtain a photo of the Chapel at that time?
• Are there any records available for the gravestones in St. Brigid's Churchyard?
• Is anyone else researching this family?
