Hi Loretta! Welcome to WikiTree.com and thank you for your question.
You did exactly the correct thing by posting a public bulletin board message on the profile in question, and mentioning it here can get everyone's attention. That was correct.
The underlying question is about naming European Aristocrats. You can read all about that here: http://www.wikitree.com/wiki/Name_Fields_for_European_Aristocrats
The specific guidelines say:
1. PREFIX FIELD: This is for a title such as 'Sir' or 'Reverend'. A man who was knighted was called Sir. Do not use this field for long titles, such as 'Earl of Angus'. Titles such as that belong in the 'Other Nickname' field. Don’t use this field for ‘King’, ’Duke’, ‘Lady’. For medieval and earlier profiles, ‘Sir’ or 'St" are almost the only acceptable uses of the prefix field.
4. OTHER NICKNAMES: This is where their title belongs (i.e. ‘King of England’, ‘Queen of Scots’, ‘Lord of Dunmow’, etc.). Titles may include numbers (i.e. either ‘Earl of Arundel’ or ‘3rd Earl of Arundel’ is acceptable). This is also where any actual nicknames (i.e., ‘The Younger’, ‘The Poor’, ‘Talvas’, ‘The Loyal’, ‘Copped Hat’, etc.) and translations such as Eléonore, Leonor, Eleanor belong. Do not put any nicknames in quotations. Separate multiple names with a comma. Do not list occupations, such as 'Sheriff of Nottingham' or 'Knight'.
9. SUFFIX: These were not generally used in the Middle Ages. Modern usage includes Jr, Sr, III, IV, and so on. For kings and queens the number should go as part of the Preferred First Name instead of in the Suffix. For example, VI is not an appropriate Suffix for King George VI.
I hope this answers your question about these special naming conventions. We all have to use the same naming conventions so that we can keep track of the individual profiles and to minimize the creation of duplicates. If we all used the name for Robert Bruce that we think is correct or appropriate, we would have many duplicate profiles for him. The mantra to remember is, "One profile per person on the WikiTree."
Thanks for a great question! Kitty
