The Yoruba present the highest dizygotic twinning rate in the world (4.4 % of all maternities). Twins are very important for the Yoruba and they usually tend to give special names to each twin. The first of the twins to be born is traditionally named Taiyewo or Tayewo, which means ‘the first to taste the world’, this is often shortened to Taiwo, Taiye or Taye. Kehinde, or Kenny for short, is the name of the last born twin. Kehinde is sometimes also referred to as Kehindegbegbon which is short for Omokehindegbegbon and means, ‘the child that came last gets the rights of the eldest’.
