According to this site I’m the only person with my first and last names in the United States, with 217,477 sharing my first name and 1,950 sharing my last name. I cheated, though, because I use a shortened version of my first name. If I used the full version 1,399,353 people share that name, the 20th most popular one in the USA.
While there are over 600,000 with my first name, there are are ZERO people in the United States with my last name. Either my husband’s family doesn’t actually exist, or it’s a pretty big witness protection program. I would ask him, but he might have to kill me.
