Townland/Civil Parish and missing family member questions

I found my GG grandmother Sarah Tarpy (23) listed in an Irish 1821 census record with her father Andrew Tarpy (50). Father and daughter are listed as living in Cahernagarry in Kilreekill Civil Parish in 1821.  

My GG grandmother Sarah Torpey/Tarpy/Torpy married my GG grandfather John Ryan in Feb 1824 in Cappataggle. Ancestry interprets the residence in the marriage record as Caherna?. I assumed it was likely Cahernagarry because of the 1821 census record?  However it could have been in the townland of Cahernagormuck in the civil parish of Loughrea, which is where all of their children were baptized.  Both records are attached here. Given that the record lists their marriage as taking place in Cappataggle, what is the most likely choice for a townland listed in the marriage cert?  

John Ryan and Sarah Tarpy emigrated to Philadelphia and Sarah arrived with her children on 9 Dec 1850 on the Thomas H Perkins ship. The passenger list indicates that John Ryan died aboard ship on the way. I have accounted for all but one of the children, Thomas Ryan baptized 30 Apr 1840 in Loughrea. 

Are there any Tarpys or Ryans out there who I may be related to? Does anyone know Thomas Ryan and where he ended up? I have tried DNA but have not had success to date with such a common name>

The marriage record is at the top of the left page of the 02431... file attached below.

The 1821 census record is the other attachment. 

I appreciate any help you can give me.
