name is a sign.

several names that Allah and His prophet love like Abdullah and Abdurrahman.

to show your islamic identity, i think u have to have islamic name... coz some western name have meaning that not allowed in islam and we have to be different with the non muslim.

you can start to look for name that suite you and u like most, example; name of prophet or sahaba and sahabiat of rasool.

if u dont want to, and ure birth name has good meaning that not against islamic rule...that will be fine..
