Jethro Dawel, a Mute Wizard

Jethro Dawel is a mute wizard born to an eccentric but thoroughly non-magical family of Dawels. He receives a visit from Professor Minerva McGonagall on his 11th birthday, just a year before Harry Potter gets his acceptance letter. How will a mute muggleborn fare in Hogwarts and the wizarding world where the views on disabilities are archaic and the views on ancestry even more so?
