Assuming that Catherine/Kathleen working in Armagh & therefore possibly born in Armagh herself, a search on Armagh records shows 2 births but the date a wee bit soon for her if child born in 1916 (that of course means nothing as we don't know what age she was at the time) also a search for Loftus in Armagh produces 2 births but both female again wrong dates ... a bit of a mystery, but then again as you know the records are a bit of a hit & miss, I'll keep looking.
