That family looks like parents William Cowell and Jane CROMWELL - see Brian Lawson's births, which include:
COWELL, Thomas Edward 27 Feb 1887 Dou COWELL, William CROMWELL, Jane
COWELL, William 22 Sep 1884 Dou COWELL, William CROMWELL, Jane
Your William's first marriage could have been to Cathn CHRISTIAN married 31 July 1866 Braddan [IGI].
LDS film no.0106189 = Christenings, marriages, burials 1861-1871
The previous film I mentioned, no.0106190 has Christenings, marriages, burials 1872-1883. So with a great deal of luck, on those two films you will get his two marriages, first wife's burial, and the baptisms. - But I'm only guessing. There were a lot of William Cowells in Douglas/Braddan.
