Eastern European Last Names

Anyone marrying someone from Eastern Europe- are you going to add an A to the end of your new last name?


My fiancé is from Bulgaria and typically Eastern European names end in A for females. It has been left up to me to decide whether I want to have the same last name as him or add an A. (E.g. Marchenkov / Marchenkova)
I cannot decide whether I want to keep it simple and have the same name as my fiancé or add an A. Getting married in November so I have to decide soon. My fiancé and his family are happy with whatever I want to do, help!
