I'm new to the fandom, could you guys help me learn the names of the members from this picture?

Left to Right:

Seohyun, Taeyeon, Hyoyeon, Yoona, Yuri, Jessica (former member), Sunny, Tiffany, and Sooyoung

The one on the left is Seohyun, the Maknae or the youngest . The next one is Taeyeon the leader. Next one is Hyoyeon the dancing queen. The next one is Yoona the face/visual. The next one is Yuri, she's the black pearl. The next one is Jessica the ice queen and she was born in America. The next one is the shortest, Sunny. The next one is Tiffany the eye smile and the English speaker, she was also born in America in the same hospital as Jessica. And the last one is my favourite, Sooyoung she is my favourite as well.
