death, members of the family, including his son Jean-Baptiste (1853–1907) obtained in 1904 the 'de' addition, which was made retroactive into the person of Jean-Baptiste Bethune (1722–1799) and all his descendants. It thus also applied to Jean Bethune. It is therefore acceptable to give his name with or without the prefix, although in their genealogies, the members of the family do not use the prefix regarding ancestors who did not use it in their lifetime. Another part of the family succeeded in adding officially 'Sully' to their name. There is, however, no connection between them and the French princely family Bethune-Sully.
