Calverts of Cumberland

In my true (dis)organised style, I strayed back into one of my Cumberland families today, which will result in some small updates sometime soon to my WorldConnect db LornaHenderson.
William CALVERT showed up as a(n incorrect) match to another on OneGreatFamily, so I thought it was time to identify him a bit more accurately to avoid a repeat.
In the process I learnt where Torpenhow and Blennerhasset were, and helped another chap with his William CALVERT, given ancestry told me that he'd claimed the same entry on the 1881 census as I did for William, the problem being that the census entry showed him as single and younger than his married chap born the same place but several years earlier.
My connection to this chap is actually his wife Martha Maria SCAIFE.
