Origin: Hebrew אִילָן
The name is derived from the modern Hebrew word for tree.
It is currently the 43rd most popular male name in French-speaking Switzerland, (2010) and the 71st most popular in France, (2009).
Its sudden popularity outside of Israel, and furthermore, outside the Jewish community is a mystery. Perhaps it was brought to attention via French cinematographer, Ilan Duran Cohen (b.1963).
The name may also be used in reference to the Welsh male name. In this case, the name is of uncertain origin but was borne by an obscure Welsh saint.
A feminine form is Ilana.
