Spelling variants are very common, until the last century spelling was not considered important at all and many people didn't read/write even up to 100yrs ago, so in documents scribes who could read/write wrote the name how it sounded to them, so each record could be written differently, once the general population could read/write themselves they would copy how the scribe of their record wrote it........ it was only once spelling became important that words including names were written the same.
We are very 'precious' about the spelling of our name nowadays but this is a 'new thing'
In so far as a whole new surname change, there are many reasons why, to 'distant' themselves from their family, to avoid or escape the law, to fit in when migrating or just as they fancied a new name
