How the name Mercy changed to Marcey

This is Mercy...

She was called Mercy by her parents and later she joined primary school at Kisiizi Primary School where the teachers taught her to write her name as Marcey. So she grew up knowing to write her name as Marcey. 

When recently she was processing a passport they found that the name which was on her national identity card -Mercy- was not the same as that on her academic documents -Marcey. From there the Ministry of Internal Affairs -where they process the passports- sent her to National Identity Registration Agency (NIRA ) -where they process the national identity cards- for the correction of her name. At NIRA they sent her to the court to make an affidavit, it means she went to swear before the magistrate that she renounces the name Mercy and that she will be called Marcey forever.

...and this is Marcey

So Mercy became the owner of a national identity card and a passport where her names are spelled as Marcey.
