Generally speaking, I use real names from historical cultures or mythology. Some of them sound weird, some of them sound like they could be names of people alive today.
Franklin Castle (I had not remembered the Punisher, and luckily no-one else did), Savard Ormorand, Kasimira Margolin, Nicolai Malaxa, Hafiz al-Tahir, Athasius Varrow.
The last genuinely made-up name I used for any length of time was made up by Ambrose Bierce, adopted by Robert W. Chambers, and made famous by H. P. Lovecraft and his circle: Carcosa.
When I create characters in games like World of Warcraft, too, I do the same: Ascanius, Catilina, Licinia, Osric, Tezcatlipoca, Coatlicue, Camaxtli, Nochaya.
