Searching for ancestors

We are researching our ancestors John Francis Maloney born circa 1866 and his parents Bernard Maloney born c1840 and Mary Maloney (née Cain) born c1840. The first record we can find of John Francis Maloney is on his sons marriage certificate and just states he came from Co Galway, Ireland. We can't seem to find a birth certificate for him with the relevant parents details so we are unsure as to where in Co Galway he was born, anybody have any ideas as to where we can find this information?

There seems to be a John Maloney in the 1911 Census living with his brother Michael Maloney and 3 of John's children in Gortnadeeve, East Creggs, Co Galway, states he's a widow which ties in with his wife dying in America in 1908. If he was living here at that time do you think this is possibly where he originated from? There is also a Mary Maloney 1901 Census in Gortnadeeve, East Creggs, Co Galway living alone, could this have been John Francis Maloney's Mother?

The next record we find of him is in a marriage record for him and his wife Honora Agnes Tigh/e in Boston, Massachusetts in 1895  which states the matching parents names and only that they came from Co Galway, Ireland.

We can find a birth for his wife Honora Agnes Maloney (née Tigh/e) in Kilcolumb townland can anyone tell us which Parish that is in? There also seems to be evidence of a Michael Tigh/e in 1901 Census in Curraghmulmurry townland, West of Kilcolumb and a Honora Tigh/e (née Keegan) in 1881 deaths in Glennamaddy, Co Galway are these all in the same parish?

Any help would be greatly appreciated.
