edit: The reason I find it an odd term is because human ancestry literally doesn’t follow a line. It always branches off, even if only to just include two parents. It’s a tree like structure, a line would misrepresent it

    Imagine a line running only down the tree connecting two individuals - that’s a bloodline

    If you can draw a bloodline from one person to the other, they are of the first’s bloodline. Your full blood siblings are not in your bloodline, though you share all of each other’s bloodlines

        Glad to help.

        It’s a weird concept outside of inheritance - for example, a royal bloodline could end because the regent dies without children. Because the upstream follows the ruler, you might have to backtrack up the bloodline to find the next heritor, which you’d call a branch bloodline

        But in modern life? It’s kinda pointless as a concept. We care about heredity and family, not bloodlines
