In what way?
I’m just wondering about the origin of the place name “Marlborough”. “Borough” is of course Anglo-Saxon, usually meaning walled city, so the question is what is the derivation of “Marl-”, and is it related to “Merlin”? It does seem rather coincidental if there is a mound/tomb that may have been attributed to Merlin, and town’s name is “Borough of Marl.” Marl- probably has nothing to do with Merlin — I am just making some wild speculating here without having researched it. I suppose the etymology could be looked up somewhere.
