Is it permissible to marry the daughter of one's paternal aunt if the suitor was suckled by the mother of the prospective bride with one full, satisfying suckling, the number of any others being unremembered?

The suckling that prohibits marriage must consist of five satisfying sucklings, according to the more preponderant opinion. Doubt concerning the number does not establish prohibition. However, it is preferable to be scrupulous and avoid marriage in case of doubt, to avoid the disagreement of those who prohibit with a single suckling.
