Yep, generally there are only 2 ways which you can search for a suitable english name for yourself - Either bookstores or websites.
For bookstores you may want to try Kinokuniya (best) and TIMES.
For websites, you may start searching through
http://www.google.com OR,
If you think the names you came across with ain't good and unique enough, you may want to change it abit here and there yourself! It's all up to you. You can create your own name, and if people mis-pronounce, correct them!
