Okay lets go in code. You are person Z and your relation is person Y.
Sisters A and B have children who are first cousins to each other (one of these is Person Zs mum).
These first cousins have children who are second cousins to each other. One of these second cousins is Person Z. The other cousin has a child. This child is Person Y.
Person Y and Person Z are second cousins once removed (the once removed shows that there is new blood so to speak in the family).
If person Z (you) were to have children, they would be th
ird cousins with person Y.
Does that make sense?
You are second cousins.
If your great great grandmothers were sisters, your common ancestors are your great great great grandparents. That makes you 4th cousins.
Your grandmother's sisters are your Great Aunts.
Yes, along with your grandfathers' sisters, if any.
Your brother's father-in-law is not related to you unless you and your brother married sisters from the same family. Then he would be your father-in-law, too.
Sisters, mother, aunts, grandmothers, nieces, cousins, etc.
go ahead if you want to marry your aunt
no problem man! enjoy
There is no word in the English language for a relationship between grandmothers of related grandchildren
Then it's your 6th cousin.
sisters are people who are related
If you have no siblings but your daughter has an uncle, he is the brother of your spouse, your brother-in-law.
