Yes, the 1841 Maughold census entry of John 70 fisherman, Eleanor 55, John 20 Seaman, James 15 Fisherman is an excellent match to John Looney md Eleanor Corteen 5 Apr 1809 Braddan, with 9 children (including 2 repeated names John & Esther) baptized in Ramsey. The census includes the youngest two bp 1820 & 1823.

However, the 1809 marriage is in Braddan. The IGI baptism at St Mathews 22 Nov 1770 to John Looney & Elinor Voughten ("or Murphy"[?]) could just as easily be him, I think..
