How they’re counted
Your first surname is your father’s first, and your second is your mother’s first. Keep going: your third is your father’s second and your fourth your mother’s second. Each parent brings their whole list, interleaved with the other’s, generation after generation.
Great-grandparents get you to 8 surnames, great-great-grandparents to 16. A gap shows as “_”.
