You are right - it is fascinating... and just out of reach!
I have thought that a logical analysis of the manorial roll surnames in space and time might produce something useful. If it has not been done by when I retire, it would be a worthy task to keep active on - at the moment I have my spare time cut out trying to service the Killip worldwide clan's genealogical interests.
I'll raise it with CMS- perhaps they know of a PhD student seeking a suitable project.
