Hello Joyce, you are quite right, anything you can think of is of importance. I don't see Rockbrook in the 1901 or 1911 cesus, just a Willbrook+a Willbrook town in the 1911. I've never heard of Willbrook either. It makes me wonder though, if Rockbrook existed in 1873, it must've been there in 1901. So either there were no houses there, which is quite possible, or the census is not as complete as we think? All feedback more than wellcome. Maggie
