It flourished in the USA between the last 50s and the first 60s due to actress Sandra Dee (b. 1942). Among others, Sandra's usage is also Czech, Polish and Swedish. In Hungarian it is written Szandra.
In response to bibi66's comment, Sandra "Sandy" Allen is 7' 7 1/4" and she is the second tallest women alive to Yao Defen.
I think Sandra sounds like a dull name. Whenever I hear it, I always imagine one of those cat lady secretaries with frizzy hair, large glasses and an extremely nasally voice.
Sandra is my mom's name and I think it is a really pretty name. I actually wish Sandra was my middle name and not Alessandra, the name she was baptized with in Italy, because it is much sweeter and understated and less ostenatious.

Also used in Portuguese, pronounced SUN-dra. I've got a cousin with this name. [noted -ed]
I guess I'm in the minority here, but I don't really like this name. It just makes me think of sand. The nicknickname, Sandy, is even worse. Don't get me wrong! I know a very nice girl named Sandra. So no offense to the Sandras and Sandys out there.

My name is Sandra Alys. My friends sometimes call me Sandy, and say I remind them of sand for some reason because my hair is like the same color as sand. I think Sandra is pretty and reminds me Sasha, which I don't like as much!

My mom's name is Sandra. She was born in Colombia. I don't know how my grandmother thought of naming her since Sandra isn't really a Spanish name. People call her Sandy sometimes.
This is the name of my older sister. Since I love her so and we are very close, I find the name especially valuable to me, though it appeals to me on its own merits. (My sister goes by Sandy.)
