As I explained before: there is no citation in any text about Panchali's pre-adoption life. This is from putting 2 and 2 together.
HV - Krishna - foster son of Nanda
HV - Ekanamsa, daughter of Nanda who grew up in Mathura. Dark in color, educated as boys were, fulfilled Krishna's mission
MBh - Ekanamsa/Kuhu, daughter of Angirasa. Named Kuhu for new moon. ie, dark. Angirasa had sons and daughters who would've been brothers and sister to Kuhu.
Chandogya Upanishad - Krishna - student of Ghora Angirasa
HV - Narada family, one of them being cousins with Nanda, Krishna's foster father. A daughter, Sannati, married to Panchal King, Brahmadatta. Multiple people from Narada family married to Panchal princesses. The male names recycled through the family are Asita, Devala, and Narada. Plus one Dhaumya we know.
MBh - Dhaumya, Devala's younger brother. Both from Narada family, related to Krishna's foster father. Dhaumya becomes priest of Pandavas just prior to Panchali swayamvara.
MBh - Narada, BFF of Vyasa
HV - Krishna brings home 4 boys for adoption by his uncle, Gandusha. One of the boys is Pradyumna. Another of the boys is called Panchala. All 4 are specifically stated to be OLDER than Rukmini. Ie, they (including Pradyumna) were not sons of Krishna/Rukmini.
MBh - Panchali, adopted daughter of Drupada. Biological parents unknown. Dark in color, educated with boys, fulfilled Krishna's mission (see Ekanamsa's CV above😆)
MBH - Vyasa, arranges alliance between Kuru and Panchal
____________________
These are my reasons for believing Panchali was Ekanamsa who was perhaps fostered by Angirasa (she didn't return to Gokul, and she surely didn't bring herself up
). Krishna met her when he went to Ghora and knew her parentage. Narada (through his family connections) knew Drupada was looking for a boy. Vyasa was looking to get rid of Jarasandha and build an empire. Krishna simply didn't want himself and his clan (which included his teacher and children AND Narada clan) to get killed and was VERY motivated to help kill the emperor without involving either Kuru or Panchal (he actually made overtures to Pandavas which were ignored at the time). Since Drupada didn't have children of his own, Narada suggested the idea to Vyasda, Krishna, and the Angirasas. Kuhu's family agreed because at some point Jarasandha would've gotten all of them if left unchecked. Or perhaps they died in one of the attacks, so Krishna brought the children to Gandusha for adoption, out of whom Panchala was probably Dhrishtadyumna who, along with Kuhu, was adopted by Drupada.
Vyasa got his alliance. Dhrishtadyumna/Panchali got a future where they could actually use their education. Drupada got his heir. Krishna got his safety. Narada got his kicks. 
P.S. This would make Pradyumna Panchali's brother.

Saying it again: this is a theory by putting all the points I mentioned. The texts where I got the info are mentioned. All of them are available online except, I think, Chandogya Upanishad.
