States 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 Sinatra), and his father may be known informally as Sr. (e. g., Paul John Teutul and his son, Paul Michael Teutul). Roman numeral suffixes can be used to name a child after another family member 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 I was named Henry II (the name again skipped a generation with the birth of Henry II's grandson, Henry Ford III). A rare case where a II whose father is a Sr. is that of former American president Barack Hussein Obama II and his father, Barack Hussein Obama Sr. Historically, when child mortality was high, a child could be named for its deceased sibling (a necronym), with or without a suffix (such was the case of Salvador Dalí). There is at least one known case of multiple siblings having the same name in modern times – that of George Foreman's five sons, including eldest George Jr. and youngest George VI. The suffix III is used after either Jr. or II and, like subsequent numeric suffixes, does not need to be restricted to one family line. For example, if Randall and Patrick Dudley are brothers and if Randall has a son before Patrick, he may
