Is it permissible for a man to marry a woman whose paternal aunt breastfed with his brother?

This man's marriage to this woman is valid, as there is no prohibited degree of kinship between them. The fact that her paternal aunt breastfed with his brother or with him does not affect this marriage. The prohibited degree of kinship exists only between the paternal aunt and the one she breastfed with, not with her sisters, her brothers' daughters, or the brothers of the one she breastfed with, unless they were also breastfed by their mother.
