The child of your great uncle is the first cousin to your mother or your father, and is your first cousin, once removed.
Your uncle is your child's great uncle and your grandchild's great great uncle. Your grandson is your uncles great great nephew.

Your aunt is your child's Great Aunt, so your child is her great niece or great nephew.

Your daughter would b related to her uncles child because they would b cousins
Your father's uncle's uncle is the son of your great great grandfather. He may be your great grandfather or he may be another brother of your great grandfather, and thus your great great uncle.Your father's uncle also has aunts and uncles from the other side of his family. That is, he has uncles who are brothers of that one of his parents who is not a descendant of your great great grandfather. Those uncles are not related to you at all.
The cousins of your in-laws are not related to you and neither are their parents. However, the parents of your spouse's first cousins are your spouse's aunts and uncles, and thus your children's great aunts and great uncles.
Cousin. Your parents brothers and sisters are aunts and uncles. and the aunt and uncles children are your cousins.
Your uncles daughter would be your cousin.
If your great uncle married into your family some of his nieces and nephews are your aunts or uncles (or your parent) and some are not related to you at all.
You are not related to your uncles wife sister. However some may think an aunt
Your aunts and uncles are the sisters and brothers of your parents. So they are "blood related." But you also call the husband of your mother's sister your uncle, and he is not "blood related." So aunts and uncles are not always really related to you.
