This is a list of last scions (individuals who were the last member of a ruling house (dynasty), or other prominent family, where heredity is the prime form of inheritance).
This may be the last person to rule a realm, sometimes leading to a political crisis, or a change in government; other times power has already passed from the patrilineal family, leaving it in a less important position when it reaches its extinction.
Illegitimacy was rarely considered acceptable to be part of a dynasty, even if recognized by the parent.
Those who were the last scions, whether male or female, are identified in bold.
As descendants of the earliest Dukes of York, Edward and Margaret may also be considered the last scions of the House of York or York branch of the House of Plantagenet, which ruled England specifically from 1461 to 1485 (with a brief pause in 1470-1471).
