Please would you look for some MIs, Donna ?

I'm looking for the parents and grandparents of the William Cowley b 1854 ish who married Elizabeth Eleanor Moore b 1860 in 1880. I think that his parents may have been William Cowley b 1829 (but baptism in 1834 in IGI unless I'm totally wrong) and Isabella Barker b 1828 England (Yorkshire ?) I can't find the family in 1871 and wonder whether William b 1829 had died and Isabella had remarried.

The IGI has a marriage between an Isabella Cowley and George Taubman in 1868 Malew, and in the 1871 census there's an Isabella Taubman, mason's wife b England, (husband absent) with several Taubman children whose parents from IGI are George Taubman and Margaret (Corlett ?). By 1881, George Taubman is a widower.

MIs for these burials might show whether or not I'm on the right track:

COWLEY, William 38 Malew 11 Jun 1867

TAUBMAN, Margaret 28 Malew 10 Apr 1864

TAUBMAN, Isabella 52 Malew 15 Jul 1880

*****************************
Also this one which might be the mother of William Cowley b 1829 (Isabella Cowley nee Bridson):

COWLEY, Isabella 57 Malew 27 Sep 1860

Thank you.
