Information sought on William D Daly.

I happened on the following. On 04/03/1865, a birth is recorded of Herbert James Daly. Farther William D. Daly, - gentleman - of Riverdale,   Ballinamore Bridge, County Galway. Mother - Letitia Daly - nee Rigby. Riverdale was initially owned by Denis Kelly. I later learned that around 1861 to 1863, William D. Daly became the immediate lessor of most of the farms/ houses in the adjoining townland of Cartronearl, Ballinamore Bridge. William D Daly continued to be the immediate lessor of Cartronearl, until round 1917, when the land was divided.

Riversdale and Cartronearl are in the civil parish of Killeroran. 

Does anybody know of William D Daly,  or his wife Letitia - nee Rigby.
