Ydra Kilwallen Sibwarra

Ydra Kilwallen was a human female (presumably from Chandrila) who was recruited into the Jedi Order. She became a padawan, but left the Order for unknown reasons sometime prior to 19 BBY. As such, she was overlooked by the Great Jedi Purge. However, although she escaped death, she was placed on a list of wanted Jedi by the Imperial Security Bureau shortly after the Galactic Empire's formation.

Ydra made her way to Chandrila where, at some point, she married a man named Sibwarra. They had a son in 11 BBY whom they named Dev Sibwarra. Shortly after his birth, in order to escape the Empire, the family moved to the small, distant colony of G'rho. She recognized Force potential in Dev, and began teaching him what rudimentary Jedi skills she knew, hoping that she would be able to find a surviving Jedi Knight to apprentice him off to.

However, it was not to be. In 1 BBY the Ssi-ruuk attacked G'rho. Dev was enslaved, while Ydra and her husband were killed or enteched.
