Leda Lestrange

Leda Lestrange was a witch who, from sometime to 1897 to 1926, had a "close relationship" with Newton Scamander while they were both students at Hogwarts School of Witchcraft and Wizardry.

When Queenie Goldstein was using Legilimency on Newt, she noted that Leda was "a taker" in their relationship.

According to Fantastic Beasts and Where to Find Them (film) director David Yates, we will learn more about Leda Lestrange, and Newt's relationship with her, in future movies in the franchise.
