Is the name "Nancy" reprehensible or forbidden by Sharia, and must it be changed according to Sharia, given the opinions surrounding its meaning and origin?

The name "Nancy" is foreign. It is permissible to be named with it as long as it is not repulsive, does not contradict creed and morals, and is not a symbol for non-Muslims. Muslims should be distinct in their names. It is wise not to rush in demanding a woman to change her name until faith settles in her heart.
