E-mail sender changing from computer to phone

[Kit-Ginevra]

This is a very odd one.When my friend Hannah sends me an email and I check it on my computer,it shows it as having come from Hannah-excellent.
When I check it on the email app on my phone(Samsung J6) it shows that the sender is now someone called Barry Hers are the only emails that this problem happens with,and whilst it's not a bother,we'd like to find out if it's my phone or her emails as she sends out lots of church emails and it gets very confusing if they appear with a different sender on.
Any advice muchly appreciated...

What is most likely the case is that somehow Hannah's email got saved as Barry in your contacts on your phone's email app. I am assuming you are using an app.

There are other possible things to check, but this would be my first go to.

Or that Barry's contact info somehow has Hannah's email address in it.
I'd go through both Hannah and any possible Barry contacts and see who got what.
