How was Mahatma's surname spelt?

MMDE: Mahatma Ghandi

Current: Mahatma Gandhi

There are a few references on the internet to Mahatma Ghandi, yet most references today spell his surname as Gandhi.

Is this the Mass Memory Discrepancy Effect in action or just a few instances of people being unsure hiw to spell it correctly so took their best guess?

The problem with the "simple misspelling" argument is that there really does appear to be many people who learned to spell it one way then suddenly, all within a short time span, all became aware they were "wrong" all along. If each individually were just correcting a lifelong misspelling, it would not happen to those experiencing it all at the same time.
