Lucy is the daughter of Henery. Grand daughter to the savior Emma and Regina. Great grand daughter to Rumple, Snow white and prince charming.Very little is known other than that Lucy traveled a very long way to seek out Henery, who appears not to know anything about having a daughter. She comes with the Once Upon a Time book Volume2. She comes to Henery (now an adult) saying that the family needs him. This was the closing of the Finale Once upon a Time Book1.We do not know yet if Henery is under a curse similar to the forget spell. A spell that never effected him in the past during all the other times it was cast. It is rumored that Once Upon a Time book2/volume2 will return in 2018 with only Regina and Rumple. The older Henery maybe the main focus along side his daughter much like hennery was with Emma.It is possible the babys will all be grown up and appear as well. Zelena's daughter (Lucy cousin), Emma's brother (Lucy grand uncle?), and Bell's son (Lucy grand uncle?). Time will tell on ABC.
