In the United States the most common name suffixes are "senior" and "junior", which are abbreviated as "Sr." and "Jr." with initial capital letters, with or without preceding commas. In Britain these are rarer, but when they are used the abbreviations are "Snr" and "Jnr", respectively. The use of these social terms is governed by etiquette but not enshrined in law. According to The Emily Post Institute, an authority on etiquette, the term "Jr." can be correctly used only if a male child's first, middle, and last names are identical to his father's (current) names. When a male child has the same name as his grandfather, uncle or male cousin, but not his father, he can use the "II" suffix, which is pronounced "the second". When the suffixes are spelled out in full, they are not capitalized. Social name suffixes are far more frequently applied to men than to women. A child with a name that varies from a parent’s name in middle name only may also be informally known as Jr. (e.g. Francis Wayne Sinatra, son of Francis Albert "Frank" Sinatra). Roman numeral suffixes can be used to name after other family members like an uncle, cousin, or ancestor (including grandfather or great-grandfather). For example, Quentin Roosevelt II was named for his late uncle, Quentin I. Similarly, a grandson of Henry Ford was named Henry II. (The name again skipped a generation with the birth of Henry II's grandson, Henry Ford III.)
