Am I overthinking ?

I am an only child and my husband has one brother. My husband and I have 2 children. My husbands brother got married recently and everyone in the family including grandparents, parents, cousins, my children (even the baby that wasn’t even in the wedding) were included in the book that they passed out for guest. Is it normal that I was not listed as I am the only “in-law”? Even the deceased family members (grooms mom and brides dad and brides special friend) were all listed in the phamplet except me. It truly hurt my feelings.
