Wow! Thanks Aughadowey, I found the last child born to James and Rose O'Donnell McShea of Loughsalt on the link you sent, number 46. Anna McShea, baptized April 2, 1877, sponsors Hugh (I think, hard to read and in Latin, perhaps you could have a go) and Anna O'Donnell. Perhaps these are the parents of Rose, or her brother and his wife. PRONI has a civil record for the death of Rose and her infant in 1880 in Meenacloghcor, so this is the first scrap of information I have that might help.
For Sarah, I send this information because this end of Lough Salt is a little cluster of O'Donnells, Brownes, Hanlons, McShees and Rogerses on the 1857 Griffiths. The townlands there are Loughsalt, Meenacloghcor, and Tievegarvlagh which can be GoogleEarthed.
My mother recently told me that her mother paid the taxes on the McShea property until 1944 or thereabouts, until my grandfather suggested she stop. Is there somewhere I could obtain that information?
Thanks again,
Kathy
