BROOKLYNf & mEnglish (Modern) From the name of a borough of New York City, originally named after the Dutch town of Breukelen, itself meaning either "broken land" (from Dutch breuk) or "marsh land" (from Dutch broek). It can also be viewed as a combination of BROOK and the popular name suffix lyn. It is considered a feminine name in the United States, but is more common as a masculine name in the United Kingdom.
EVELYNf & mEnglish, German From an English surname that was derived from the given name AVELINE. In the 17th century when it was first used as a given name it was more common for boys, but it is now regarded as mainly feminine due to association with the related name Evelina.
JOCELYNf & mEnglish, French From a Germanic masculine name, variously written as Gaudelenus, Gautselin, Gauzlin, along with many other spellings. It was derived from the Germanic element gaut, which was from the name of the Germanic tribe the Geats or Goths, combined with a Latin diminutive suffix. The Normans brought this name to England in the form Goscelin or Joscelin, and it was common until the 14th century. It was revived in the 20th century primarily as a feminine name, perhaps an adaptation of the surname Jocelyn (a medieval derivative of the given name). In France this is a masculine name only.
