In most states, your name change should include the easy ability to change your surname. Of course, this varies from state to state, I would imagine. The good news is that you can check it out right online quickly and easily for your state.
As for me, I'm changing the whole kit 'n kaboodle. The adoptive family legally disowned me because way back when, I didn't become their boy-genius, hot-->-bleeped-<--career cracker jack who did them proud. You believe that s---? F--- 'em! I have no family. Surely, you can change your last name in your state too. We can do it easily here in Oregon.
Surely, most of you are faring much better than this. I certainly hope so. Thanks.
