Joan
The name Joan is a derivation of the Hebrew name Johanan, which means 'God is gracious'. It became popular in Europe after the Bible was translated into languages other than Hebrew and Greek.
In the Middle Ages, Joan was a common name for both boys and girls in various European countries. Over time, it became predominantly a feminine name.
The name Joan has been borne by several notable figures throughout history, including the famous Joan of Arc, a French heroine and Catholic saint who led the French army against the English in the Hundred Years' War.
While Joan is traditionally a feminine name, it has been used as a masculine name in some cultures and time periods, though it is now quite rare as a boy's name.
