Is it permissible to marry the daughter of the paternal cousin's son, who is also the daughter of the paternal uncle's daughter?

It is permissible to marry the daughter of a paternal aunt's son and the daughter of a paternal uncle's daughter, because there is no prohibitory degree of kinship between them. The daughters of paternal uncles and aunts, and the daughters of maternal uncles and aunts, and their daughters, are permissible for marriage. A man referring to such a girl as "aunt" is merely a customary term and does not entail the prohibition of marriage.
