Lambston seems a pretty simple name, but the table below shows the variations in name that I have found during my research. I think it is pretty clear that it has mutated and simplified over the years from some version of ‘Lamberteston’ to ‘Lambston’. Some of those names listed below are probably copying errors in documents but some appear frequently enough to suggest real change.
