Mine is Duke Neaj Peterton II

How to work it out:

For your title, use one of the following:
Duke/Duchess
Baron/Baronness
Lord
Sir/Lady

Secondly take your first name and reverse it, eg. mine is 'Jean' so backwards its 'Neaj'.

Thirdly, take your middle name and add one of the following on the end:
- ton
- ford
- burgh
eg. my middle name is 'Peter' so its 'Peterton, 'Peterford' or 'Peterburgh'.

Last of all the number on the end specifies when you were born. For example if your parents had three children and you were the second to be born, then you will have the number 'II' on the end. If you are the sole child then you can either just put 'I' or nothing at all.
