Colin (given name)
Colin is an English-language masculine given name. It has two distinct origins: As a surname, Colin can be derived from the given name, but can also be of unrelated (French) origin. The Irish patronymic "Ó Coileáin" gave rise to the surname "Cullen" (which is also the anglicization of the unrelated patronymic "Ó Cuilinn"). In England and Wales, "Colin" was one of the Top 100 most commonly given male names for most of the 20th century but declined greatly at the end of the century and since. It rose steadily from 96th in 1904 to 82nd in  1914, 61st in 1924, 26th in 1934 and 15th in 1944. It then declined to 22nd in 1954, 25th in 1964, 44th in 1974 and 67th in 1984. The decline then accelerated and "Colin" ranked 319th most popular name England and Wales in 1996 and 684th most popular in 2014. It has been moderately popular in the United States and was listed in the top 100 boys names in the U.S. in 2005. In Scotland it ranked 302 in 2014, but in Ireland it is more popular, ranking 88th in 2006. In the US, "Colin" peaked in 2004 at rank  84, but has substantially declined since (rank 196 as of 2016). The form "Collin" reached the peak of its popularity somewhat earlier, at rank 115 in 1996, and has declined to rank 298 as of 2016. Taken together, the names "Colin" and "Collin" accounted for 0.16% (about 1 in 620) of boys named in the US in 2016, down from 0.4% (one in 250) in 2004.
