When I bought my iPad, somehow the Apple store set up my @me.com account with a display name which is my husband's. I think I am using the correct terminology here, but to make it clear, when I send a photo from my iPad (for example), the recipient sees the sender address as "RICHARD XXX <my email address>". I have gone to "Settings/Mail, Contacts, Calendars/Brenda's Email/Name" and the indicated name is my own. I erased it and reentered my own name, but this made no difference. The help desk at the Apple Store did something I could not follow on the iPad and said that would fix it, but the problem remains the same.
How can I change the display name to match my own so my contacts don't think that my husband is sending the email when it's really me?
