Does branwen have children

Branwen, a character from Welsh mythology and the Mabinogion, is known for her tragic story involving her brother Bran the Blessed. In the tale, she marries the King of Ireland, but their union leads to conflict and strife. However, Branwen does not have children in the traditional sense; she gives birth to a son named Gwern, but he meets a tragic fate early in the story. Thus, her legacy is more tied to her family and the consequences of her actions rather than a lineage that continues through her children.
