Hi,
I know about this site. I don't find it useful and question the purpose of the research. It seems to try to place an academic thesis behind being able to state where names originate from. At best, it can claim to state the distribution of any particular surname based on a particular census and modern day post codes. It can't claim to be able to state the origins of a name.
In fact any of us could produce the same sort of thesis, simply by looking at the distribution of any surname, say on the 1841C and then claim to be able to state the origin of the name.
For me, this isn't a means to be able to state the origin of any name.
Sorry to be so critical but this site is just a toy.
