Well, in that case . . . here goes.
I guess these names are "up for grabs" to any who need Celtic- or Latin-sounding names.
All of them come from Sherrilyn Kenyon's
Character Naming Sourcebook (the earlier edition, from 1994). Currently there are 50 female names and 77 male names, collected below. I have so far consulted the Arthurian Legend (AL), Celtic (C), and Welsh (W) names lists, but can also move on to the Gaelic, Irish, Latin, Scottish, or Teutonic lists. Everyone, just let me know if you'd like more from which to choose.

After each name, I have typed the meaning Kenyon provided (if any), although for Arthurian Legend names, she gives only a reference as to the
type of character or place to which a name was assigned (e.g., "a king," "a mountain," "a burial place," "a knight")--no actual etymology behind the names.
I have paid special attention to those that had the same sound as the elven names you're already using, QF, as well as to any that meant "soldier," "warrior," "strong," "shield," ETC.--just as you requested. The "warrior/strength" names are in case you wish also to choose from this list, the names of the soldiers for your army--not just the names of your elves.
Let me know if I should keep looking, or if you've changed focus (i.e., if you would like me to look for names with other meanings than you specified before, or with a non-Latin, non-Celtic sound).
