Didn't find as much as I'd hoped

A Bridget Power, age 77, born Co. Waterford, married, died 23 July 1873 Cunard? Sr., informant's name hard to read but interestingly the next entry is for a Bridget Power (age 38) on the same date but different address (informant Wm Power).
I see that Nicholas Power's 1938 death certificate fives parents as Patrick Power & Mary Sheehan but Nicholas' daughter may have just given her mother's name rather than her grandmother's name.
Nicholas' name didn't ring any bells at first but then I realised that he was involved in the investigation of the murder of a connection of my grandmother's which was quite a sensational case at the time and even recently has been written about and disputed.
