Looking for Hugh & Roseanne McManus

My great grandparents, Hugh & Roseanne McManus are listed on the 1901 Census as living on Brooke Street in Enniskillen.  Hugh was a relieving officer.  I can find no trace of them on the 1911 census.  I know they were both living in 1911. I found an obituary for Roseanne listing her death date as June 16, 1923 and giving her address as Mary Street, Enniskillen.  Hugh died on July 30, 1924 and was living on Cross Street, Enniskillen at the time of his death.  They are both buried in Convent Cemetery in Enniskillen.  Some time in 1923 one of them was hospitalized at the Enniskillen Dispensary.  I know this because I found a record of my grandmother, Annie Galligan, their daughter, travelling from the US to visit someone in the Enniskillen Dispensary. 

Any information will be greatly appreciated.
