If both are christians I think there is no problem. They are not blood relatives the only relationship they have is through your marriage
Your mother's sister is you aunt and her husband is your uncle, but his brother (younger or older) is not related to you. If you are an adult female you can marry him if you want, although some religious and cultural groups would find that unacceptable. If you are an adult male you could also marry him, but only in those few places that permit same-sex marriage.
