But that doesn't answer why did the actual name change for it to be on the gravestone. I can understand spelling mistakes on documents but not for them to actually be carved in stone. The same with marriage certificates.
But which variant is the "real" name?
Who decides what the "correct" spelling is?
Take my own name - Garrad.
Many RC'ers call me Garrard!
I get post all the time addressed to Garrod, Garrett, Garrard, Goddard, even Gadd!
I will repeat my earlier assertion:
Spelling is an art-form; not a science
