Fergus McInerney - Farmer at Hollymount, Cappard/Kilthomas, Galway

Hello, I appear to have hit a wall in my family tree due to lack of records on one family member - Fergus McInerney.

My family has a long family history as farmers and in particular at Hollymount, Cappard/Kilthomas, Galway. My great-granfather John Brody (bn 1882 from Scarriff/Killanena, Co Clare and also a farmer) married into the McInerney family by marriage to Bridget McInerney (bn abt 1884) and took over as head of the Hosuehold at Hollymount where they lived with Bridget's widowed mother; another Bridget McInerney (bn abt 1858). There they had my Grandad, John Brody and his siblings Fred, Patrick, Delia (also Dilly) and Catherine (also Kitty).

Now where I am getting stuck is on who my great grandmother Bridget McInerney's (1884) father was / Bridget McInereny's (1858) husband. From my great grandparents marriage certificate I can see that he was called Fergus McInernery and he was deceased at the time of their wedding which was 1911 only 2 months before that years census. Bridget McInerney Senior also appeared as widowed with her daughters Bridget (ggm) and Mary on the 1901 census so he was deceased by 1901. The ONLY other record I can find of him is a dog registry for the farm in 1878, so I know that he was alive in 1878 and dead by 1901 basically but I cannot find any birth, baptism, death, marriage or funeral records for him anywhere and so its causing me a wall. His wife's maiden name (Bridget Snr) was Loughrey and this tallys up other records of her parents who were Michael Loughrey and Anne Welshe of Kilbeacandy/Gortacarnaun. 

Rather confusingly though it appears Hollymount was more of an estate with several buildings housing several different farming families - one of which was another family of McInenery's in another house at Hollymount and rather awkwardly (for me in my search!) a further couple of Bridgets of similar age! They were however a considerably bigger family with a fair bit of USA/worldwide emmigration though and I think unrelated to my McInerney side although they lived in close proximity.

If anyone could advise where else I can look for records on my 2nd great grandfather Fergus McInerney that would be wonderful! So far he's is only mentioned on an 1878 dog register, the marriage certificate of my great grandparents and also an amended note added to a 1851 census registry for some reason.
