Also the reason Tweed wants to know how they contacted the Jedi is because for the 9-12 years they have been on the run/in hiding. So it wouldn't make sense for them to be easily contacted. You need a way "in" having a Chiss Jedi who was passing through, or an Jedi who was passing through who gave them a number to call when it was time makes more sense.
Shoot Tweed a PM once you make the fixes. But I'd say there was a Chiss Jedi who discovered her and sent her information to the Order and told her parents to contact the Jedi when she was read to join.
