Sorry to disagree but, of all the Registers that SWMBO has transcribed, I can't think of, in all those many thousands, of any reference to 'Landowner'. Indeed, this record, showing what appears to be 'street address' also infers otherwise. For a 'landowner', I would expect something like Manor, House, etc, to be dominant in the address.
In fact, I'm not convinced that the first letter is an 'L'. With the miniature 'v' at the top, I'm more inclined to see it as a 'T' as in 'Tradesman'.
EDIT: Flook got in before me. DOH!
