If you want, you can add your married name of "Gardner" in the Current last name slot. Your maiden name needs to stay at LNAB or "Last Name at Birth". When and if you decide to do that, your name will show as Rose (Starks) Gardner. You do not have to add the ( ); they are automatically added when you have both maiden name and current or married name on your profile. The search engines will still pick you up as Starks.
