natural sons

Children born unwed

Natural sons are male offspring born to parents who were not married to each other at the time of birth.

The term appears primarily in legal, historical, and genealogical contexts, where the distinction between legitimate and illegitimate children once carried significant consequences for inheritance and social standing.

The duke acknowledged his natural sons but could not make them heirs to his title.

The phrase is less common today as laws have largely eliminated legal distinctions based on parents' marital status.
