Names with different spelling.?

.So my friend has been told the meaning of a name depends on how the name is spelt. She keeps asking how true this is but I have no answer for her Lol for exsample the mame Crystal can be spelled Crystal,Krystal, Kristal, Christal (and more ways) so all different spellings will have a different meaning? I didnt know the spelling of a name had anything to do with the meaning of the name. Thanks for any opinions.
