Enter how many generations each of you is from your shared ancestor, and get the exact cousin degree and removal - first cousin, second cousin once removed, and so on.
Count the steps from each person up to the shared ancestor: a child is 1, a grandchild is 2, a great-grandchild is 3, and so on.
"Removed" describes a generation difference between cousins. Your first cousin's child is your first cousin once removed - same cousin line, one generation apart.
Count each parent-child step. If your grandparent is the shared ancestor, your parent is 1 generation away and you are 2 generations away.
That means that person IS the shared ancestor's child, so the relationship isn't a cousin relationship - it's siblings, or an aunt/uncle-niece/nephew relationship, depending on the other person's distance.
