Newtina

Newtina is the het ship between Newt Scamander and Tina Goldstein from the Fantastic Beasts and Where To Find Them fandom.

Canon
Newt and Tina met in 1926, when Newt was visiting New York. Although they didn't start off on good terms, they became closer during their search for fantastic beasts and eventual encounter with Gellert Grindelwald. Afterwards, Newt said goodbye to Tina.

At some point, Newt and Tina got married. They had at least one child (presumably a son). They had a grandson called Rolf and great-grandsons called Lorcan and Lysander.

Fanon
Although known to be canon for a long time, Newtina wasn't a popular ship until the movie Fantastic Beasts and Where to Find Them, as this marked the first proper appearance of both Newt and Tina.
