Jemma

In Marvel's Agents of Shield, Jemma Simmons was a biochemist and was part of Phil Coulson's team. She worked closely with Leo Fitz, and the two were commonly referred to as 'Fitzsimmons.' Jemma had two PhD's and attended S.H.I.E.L.D's Academy of Science and Technology. Grant Ward attempted to kill both Jemma and Fitz. Fitz sacrificed himself to save Jemma, telling her that he loved her as he did so. Fitz survived with some brain damage, but their friendship was never the same due to the guilt Jemma felt for his sacrifice and because she did not reciprocate his feelings. Jemma was sucked into an obelisk that was a portal to another world.

Jemma is a variant of the Italian name Gemma which means 'gem or precious stone.'  In 2014, Jemma was the 637th most popular name for girls in the U.S.
