I was going to try and give playing a Captain a shot, and decided I may as well use the Bree Nationality as it would be the easiest to piece into the existing world without too much stretching. The problem comes with the simple names, as most will already be taken. I thought about digging into other names, but am not really an expert and not sure if what I find wil be appropriate. I usually google medieval names, which is how i came upon this one. It doesn't really fit, and none of the norse names I've dug up for other uses would really fit either.
How did you all get by with unique names while still following the Bree "Guidlines?"
One of my characters is a Man (well, Woman) of Bree too, and I just tried out "old fashioned" names until I found one that wasn't taken. Generally, any name that isn't too obviously modern or related to real world religion (no "Christians" or "Christines") should do. Sorry if that isn't helpful.
Norse names aren't necessarily unfitting for Breelanders IMHO, though I would reserve the names most obviously of that origin ("Leif", "Brynhild" or the like) for Men of Dale.
In the past I've found Welsh names that aren't taken in Lotro and, to my non-expert eye, seem to fit in just nicely. The shorter ones at least; some of the longer ones look better suited for an Elf or Dunedain
