when i recieve an email from my I-cloud account it has a mispelling in my name (the E-mail address is correct)

When i receive an email from my I-cloud account it has a mispelling in my name (the E-mail address is correct but one letter of my surname is incorrect ). When i go into my account settings and my personal information is all correct ?

I just cannot see where this mispelling is to correct it, i have tried settings in Mail on the web I-Cloud website ?
