i have been studying Quenya for some time now, but unfortunately i have no idea what your name is in Quenya..there is a word 'sar' meaning "small stone" but that won't help much i think..i think that's not what you mean.. You can go to the following site for some fun when it comes to names, (you'll have to fill in your first and last name, but it just works on the first and last letter of your name..for example, Sara
would be Merenwen, but Sarina
etc. would be too....so...but you can take a look:http://www.chriswetherell.com/elf/Default.asp
Sorry i couldn't help you out more there!
