Welcome to Ireland Reaching Out!
I located a few records pertaining to Cathy's family. Here is the 1911 census record for the John Kenny family including 17 year old Patrick. http://www.census.nationalarchives.ie/pages/1911/Galway/Ballymacward/Alloon__Upper/448866/ You can see the house number was 13. The house numbers were assigned by the RIC constable as he went thru the townland picking up completed townlands, The first house he visited was house 1, second house was house 2, etc. The Kennys were in the same house for both censuses. I located the civil death records for Michael and Bridget Cannon see two links below. I was unable to find a civil marriage record for John Kenny and Catherine Cannon but did locate a church record.
On the subscription site Roots Ireland I found a potential lead for baptismal record for John Kenny. See transcription below. I was not able to find a lead for Catherine's baptismal record or the marriage record for Michael and Bridget.
