Lord of the Manor?
Laird?
These titles can be real, but if you buy from ebay all you’ll get it instructions on how to change you name by deed poll to “Lord John Smith” (where Lord is a first name) or a certificate granting you a short lease of a square millimetre or land in Scotland.
One point to note about changing you name: you cannot use a ‘title’ in your new name in such a way as to infer that you are ‘Lord’, ‘Earl’, etc. Most organisations will not recognise such a name change.
