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 call his son "Patrick II". If Patrick now has a son, his son is "Patrick Jr." (or "Patrick III"; alternatively, "Patrick II" if Randall didn't have a son named Patrick II). As time passes, the "III" suffix goes to the son of either Patrick Jr. or Patrick II, whoever is first to have a son named Patrick. This is one way it is possible and correct for a Junior to father a IV. Another example involves President Ulysses S. Grant and his sons Frederick, Ulysses Jr., and Jesse. When Frederick's son Ulysses was born in 1881, Ulysses Jr. did not yet have a son named after himself. Therefore, Frederick's son was Ulysses III. Ulysses Jr.'s son, born afterwards in 1893, was Ulysses IV. Jesse's son Chapman was the father of Ulysses V, as neither Ulysses III nor Ulysses IV had sons named for themselves.
