Hi Vicki
The William and Catherine one looks like it could be further investigated. The age of the children suggests a possible second marriage - Williamina is 4 and there is a younger sibling aged 2. Then a big gap - 10, 12 and 14. The eldest daughter (14) is called Ann. It might be that the informant on the death cert could have mixed things up
I don't see any other families that come near to matching your criteria, otherwise. Also, the family could have emigrated before 1861.

Added - checked the 1851 and the parents are William and Catherine, so my theory of second marriage doesn't seem to work
