Let me see.... if Madelyn Payne and Anna McCurry were first cousins, Anna’s children and Madelyn were second cousins. So, Madelyn’s child, Stanley Ann would be Anna’s third cousin. Stanley’s child would be Anna’s fourth cousin.
Is that what once removed means? I am not familiar with that term.
Do you have a cousin? Does that cousin have any children? They are your first-cousins once removed.
By the same token: The cousins of your parents are your first-cousins once-removed.
