Take the name, Elizabeth. In addition to the history of the name and trends associated with it, there are also 34 short and pet forms and 10 cognates listed.
Anyway, it is fun to read, learn about other cultures names, and sometimes you learn something unusual. This entry, tickled my funny bone:
OMAR (m.) English: biblical name borne by a character mentioned in a genealogy (Genesis 36:11). It has been occasionally used since Puritan times down to the present day in America. More often, however, it is of Arabic origin, as in the case of the film actor and internationally famous bridge player Omar Sharif (b. 1932 in Egypt). (emphasis mine)Only the O.D.F.M. would assume we're all stacking our Fantasy Bridge Leagues with Omar Sharif. Laugh out loud.
