Does the suckling not become the maternal uncle of the wet nurse's mother if he suckles from the grandmother of the one he wishes to marry?

If the questioner was nursed by his maternal grandmother, then his maternal aunt's daughter becomes unlawful for him, because she has become his sister through suckling. However, if he was nursed by his paternal grandmother, she does not become unlawful for him unless there is another legally recognized suckling. The suckling that establishes prohibition must consist of five sucklings, according to the preponderant opinion.
