Mary

Mary is Socko's cousin, who was mentioned in one of Spencer's blogs on iCarly.com. Spencer had a huge crush on her for many years, and because of this, he only reluctantly agreed to attend her wedding.

During the wedding, he did several inappropriate things, listed in his blog post, What NOT to do at a Wedding.

Unlike most of Socko's relatives, Mary's name isn't related to her occupation. It is, however, related to the situation she was mentioned in, because she was getting married when Spencer wrote about her.
