Samantha "Sam" Liara McGonagall (b.25th October, 1979) is a Half-bloodScottish witch born to William and Felicity McGonagall (née Sinclair), she and her twin Arya are the couples eldest daughters, they also have a younger brother Wyatt McGonagall and a younger sister Flora McGonagall. Through her father she is the granddaughter of Minerva McGonagall and Gladwin Morgan.
She attended Hogwarts School of Witchcraft and Wizardry between the years of 1990 and 1998 Where she was sorted into Gryffindor after much deliberation from the Sorting Hat (having already been mildly exasperated thanks to her sister). It deliberated for 5½ minutes between Gryffindor and Slytherin, before deciding that Samantha, like her grandmother before her, could do great things in Gryffindor.
