Trying to find information about the parents to move the line upwards

Parents- Thomas Quine who married Isabel Corkill (both born before 1761)

Children born Braddan

Margaret August 3 1777 (Buried Braddan 14 Aug 1794)
Matthias April 25 1779
William October 7 1781
Isabel Feb 15 1784. (Buried Onchan 4 Jan 1813)
Elizabeth December 27 1785
William October 7 1781 (probably died young before 1791)
William January 30 1791
John June 16 1793 (married Margaret Kelly in Braddan)

On the parents this is what is known:

Mother: The Braddan register says "Isabel Quine ny Mealey als Corkill to Conchan". It seems "ny Mealay" would mean "of .....with a place name. (Nearey will be from yn Eary - the hill pasture, Corkey is oates. Found a reference to a place named Mealey in Lezayre, but there may be another?)

Father: John.... I thought he would be from Oncan before Braddan but I am no longer sure.

Any information upwards or where they are living in Braddan around the 1790's would be appreciated.
