Can he marry the daughter of his mother’s paternal uncle?

Is it permissible for me to marry the daughter of mymother's paternal uncle?
Praise be to Allah.
A person's paternal uncle is the paternal uncle of all his offspring,
because the paternal uncle is the brother of the father or
grandfather. So the mother's paternal uncle is regarded as a paternal
uncle to her children, and his children are paternal cousins to the
children of that mother. Although in some cultures they call them
maternal uncles andaunts, this is just a customthat is followed among
some people; it does not carry any weight in terms of sharee'ah or
linguistically.
Based on that, the daughter of the mother's paternal uncle is
regardedas your paternal cousin, and the daughter of a paternal uncle
is not a mahram, so there is nothing wrong with you marrying her.
