Margaret,
Further to the previous messages, I found this marriage record on irishgenealogy,ie. This seems to be the relevant record, which shows his father as Patrick (who was dead), and his father-in-law a pawnbroker. A further search on the subscription site rootsireland.ie shows a Patrick Doyle with father Patrick baptised at Lemanaghan parish in 1840. This is the only suitable record in Offaly. Margaret Daly was his mother.This record would indicate that Mary Anne may have been from Longford, as it was traditional for a marriage to take place in the parish of the bride.
Best wishes, Kieran
