Neither name is difficult or has any extra vowels etc. But every year MIL spells their names wrong. Even though she receives cards with their names on them. This year I wrote on her christmas card and spelled the girls names in block letters and underlined them. Hopefully that will clear things up BTW - Shes not that old or senile, I think she just does it to annoy me, or she doesn't care.
I remember as a child getting annoyed when people spelt my name incorrectly. Maybe it's just me
