When children are registered, they are often too young to spell their own names. A parent, who is often illiterate, will spell the name for the child, as best as the parent can. In time, the spelling may be determined to be incorrect because a family member learned how to spell it correctly or the child's birth certificate has been found (if there is one). Additionally, in many cultures there is more than one correct way to spell a name; therefore, a child's case study may give different spellings each time it is processed.
