Is it permissible for a young man to propose to his maternal aunt's daughter? And thank you.

If the question is about the permissibility of a young man proposing marriage to his maternal aunt's daughter, the answer is permissible. And if the question is about the permissibility of the son of a maternal uncle marrying his paternal aunt's daughter, the answer is permissible because she is not among the forbidden [women] mentioned in the Quran, provided there was no fosterage between them.
