LOL. My sister and her husband wanted her son named after his father but was adamant that no one would call him "Junior". To help prevent it, they opted for "II". In the hospital they told her "II" is reserved for naming from another family member, usually an uncle (which she already knew)." She still insisted on "II" so that's what is on his birth certificate. No one has ever called him "Junior".
Other than that my wife can name the others Moonbeam for all I care.
