Ramsay attended Hogwarts of Witchcraft and Wizardry from 1991-1998 and was sorted into Ravenclaw House. In his fifth year, Ramsay joined Dumbledore's Army, an organisation taught and led by Harry Potter, of which he became an important member. He participated in the Battle of the Department of Mysteries (1996) and the Battle of the Astronomy Tower (1997), after which he went dark after leaving Hogwarts.
Ramsay went undercover under the name "Theodore Modest", a word play on his two middle names; "Modestus" and "Theodorus". He aided Harry Potter and the Battle of the Seven Potters and escaped relatively unscathed. When the Ministry fell, Ramsay fled and was not heard of since. However, Ramsay resurfaced after he successfully infiltrated Malfoy Manor while Transfigurated as Death Eater Antonin Dolohov, apparently attempting to rescue Luna Lovegood and Garrick Ollivander, not knowing that the trio was also imprisoned there. He later accompanied his cousin Donovar in attempting to locate one of Voldemort's Horcruxes. Afterwards, he returned to Hogwarts and participated in the final battle of the Second Wizarding War.
After the war, Ramsay finished his education and became a Magical historian and eventually married Leonora Prewett, a long time girlfriend of his, with whom he had twin children, Maximillian and Miranda.
