Also found the 1841 census with this:
1841, Patrick
Class H0107; Piece 1465; Book 10; Civil Parish Patrick; Enumeration District 4; Folio 11; Page 18
GSU Roll 464357

Thomas Shimmin - age 80 Ag Lab
Philip Quayle - age 25 Ag Lab
Margaret (Shimmin) Quayle - age 30
Ann Easemer - age 10 translation bad
Ana Cullin - age 5 believe should be Ann Crellin
Mgt Bruene - age 5 translation bad
William Quayle - age 3
Mgt Quayle - age 2

Possibility for Philip Quayle is the 22 Mar 1812 Patrick son of John Quayle & Ann Waterson

Not sure if the Thomas Shimmin is a father, uncle or grandfather to Margaret.

Perhaps address of Ballacosnahan is the clue to this family - the family is in this area in 1841 & 1851 respectively
