Dorothy Newby (Danby) wrote to Gill Jackson with
this fascinating piece of information:
'This modern place-name contains the name of a
Scandinavian heathen god - Othin. In the 12th. Century it was recorded
as "Othenesberg", i.e. "hill dedicated to Othin"
The Old English 'g' was, eventually, sounded as 'y' which gave us the
"berry", while Othin, over the course of the years became
Ose, and so we had Oseberry. The settlement nearby was, apparently
often referred to as "Newton-under-Oseberry" and it is the
'r' from "under" which moved over to the
"Oseberry" giving "Roseberry". The word
"Topping" was added much later and simply means
"hill-top" '.
As the saying goes; "Not a lot of people
knew that!"
