You can use this forum thread to request names to be added into V3. All options for first name are available for last name as well and vice versa, so please write just the name you want (regardless if it is a first or last name).
This thread will be looked at periodically. Please refrain from making multiple posts consecutively, I will post a comment everytime the names were updated so that if you do have more, you can create another post to add more rather than editing a previous post (that will no longer be looked at).
