Zandra
When unconventional British fashion designer Zandra Rhodes, the Swinging London's 'Princess of Punk,' changed her first initial from S to Z, she transformed a diminutive of Alexandra into a legitimate name, anticipating the Zander phenomenon by decades. It's name that is still rarely heard and might be worth considering as a way of zipping up a namesake Sandra.
Zandra did actually invade the lower depths of the US popularity list three times--in 1953, 1970 and 1971.
