Okay, working off the Legends Canon, I think the lore is pretty clear on where the Jedi descended, from the original
Je'daii Order. The Je'daii Order itself being originally made up of Force Users gathered on Tython by some automated ships called the
Tho Yor (their origin remains a mystery as far as I know).
Now, if you want to play with the idea of having your character or your family descend from Jedi, perhaps you should look into the
Ysanna. Based on Ossus, they are a race of Force Sensitives largely descended from Jedi stranded on the planet after a disaster. I think that's just about the closest to a Jedi "race" you'll get.
