In this article from Disneyland News we learn that Tinkerbell has a sister - Periwinkle.

Introduced in the upcoming film “Secret of the Wings,” the “frost fairy” Periwinkle is intrigued by the other seasons once she meets a warm fairy (her sis Tinker Bell), and she becomes eager to make new friends beyond the Winter Woods.

Will Tink's flight at the beginning of Wishes become a sister act?   Maybe Donald has a brother nobody knew about.  Is Disney planning to introduce more previously unknown family members?
