I think titles in front of first names and in the last name is really awful. It makes it harder to "match" with already merged trees. I have been working through the Plantagenet mess and have been moving the titles out of the first and last names like "Sir Knight John / 1st Earl of Such-N-Such / Plantagenet of Cornwall" It's really unnecessary. It should read John Plantagenet, Knight of Cornwall, 1st Earl of Such-N-Such.
I've been doing this as I work through the Plantagenet line, but I do notice that others also working in there keep adding in a display name, but it is confusing especially if there are 2 John Plantagenets of 2 different generations erroneously merged under the same father. I have to keep fixing it so I can merge the correct people and detach incorrect people...and match them to the correct parents later.
I find if I do it this way, then those that working through the Plantagenet tree and merging are actually merging the RIGHT people because I've taken the display names out and used the titles in the suffixes.
