Have a relations question?

Question

I know that my Mom's Aunt is my great aunt. But what are my great aunt's kids to me?

Great cousins? Second cousins?

And what of their kids? What are they to me? Third cousins?

Answer 1

Start with your mom and work down. Your mom is first cousin to her aunt's children. You are one generation removed from your mom, so you are first cousins once removed to your great aunt's children.

Children of first cousins are second cousins, so you are second cousin to your great aunt's grandchildren.
