I have "my" William only married to Mary Blenkinsop - but, as I mentioned, there were several Williams Casson buzzing around and marrying at about the same time.
Mine was a joiner throughout, and his marriage seems to have had some problems, because they are apart at at least one census, but when he dies, she is still inherits.
There are a few more William Cassons of around the right age - varying from 1812 to 1823 birthdates - who married various Marys, and often families of the two William & Mary couples get mixed and are combined.
I spent years tracing every William Casson line through all the censuses, baptisms, marriages and burials and other records to get them all sorted out - I think I may still have the files of the "wrong" Cassons all worked through, somewhere, in paper files, including the Kendal ones, but I'd have to spend a long time finding them. I'll have a potter around and see, but it'll not be quick, but I will get back to you in time. I did the same with a Fisher line, up there, some Ross people and some Newbo(u)lds, and it's a lot easier than you might feel, if you trace each line through and untangle them for yourself. (Several online trees have some really creative families!)
It'd be a whole lot easier tracing families around if they'd be a bit more imaginative in their names, wouldn't it?
I think there are quite a lot of people related to our Cassons, around -0 just I don't know many personally. Didn't think "oodles" was a very northern expression, used it all my life.
Lets all keep hunting.
