I presume you have eliminated Henry Cubbon & Ann Quirk - Cubons in Jurby are conspicious by their absence except for Henry Cubbon bur 22 Mar 1842 age 65 and Ann (? nee Quirk) bur 25 Jan 1865 age 87 - there is a Tomas Cubbon bur 28 Jun 1882 age 82 and a Margaret Cubbon bur 14 Apr 1886 age 83
These latter two can be found in 1881 census as retired farmer (born Arbory) and wife living at Sulby Bridge (which is pretty close to Jurby border) - suspect this is Thomas son of Henry + Ann.
