Can someone explain how second cousins twice removed work?
Your second cousin, twice removed, would be the grand-child of someone who shared a grand-parent with you. The degree of relatedness indicates the distance between one of the persons and the nearest common ancestor. You share a grandparent with your first cousin, and a great-grandparent with a second cousin. The remove indicates the number of generations between the two persons. So your first cousin’s child is your first cousin, once removed. Your cousin’s grandchild is your first cousin, twice removed. Your second cousin’s child is your second cousin, once removed. Your second cousin’s grandchild is your second cousin, twice removed.
Your cousins are your uncles/aunties children. Your second cousins are your parents cousins. Your third cousins are your parents second cousins OR your second cousins children. Another way to look at it is. Your cousins are you parents siblings children. Your second cousins are you parents, parents, siblings, children ANOTHER way to look at it is. Your cousin is your parents siblings children. Your second cousin is your grandparents’, siblings children. Your third cousins are your grandparents’, siblings children’s children.
