During the Second Wizarding War, when Lord Voldemort was in control of the Ministry of Magic, the Cattermoles came under scrutiny because Mary Cattermole is a Muggle-bornwitch. Harry Potter, Hermione Granger, and Ron Weasley freed her from the Muggle-Born Registration Commission and advised the Cattermoles to flee the country while the Death Eaters were in power. It is unknown if they took this advice.
