Is it permissible for me to marry a girl who suckled with my paternal aunt?

The question is vague, but suckling establishes the same prohibitions as lineage. So, whoever suckles from a woman becomes a son to her and to her husband, who is the source of the milk. If you suckled from the girl's grandmother or from her grandfather's milk, then you have become her paternal uncle through suckling, and thus you cannot marry her. However, if you shared suckling with the girl's paternal aunt from a woman who does not create a prohibition for the girl, then the aunt has become your sister through suckling, and this does not prevent you from marrying the girl. The suckling that establishes prohibition consists of five fulfilling sucklings.
