On Google Calendar, when I add guests to an event, a pre-populated list of emails to choose from appears. Where is Google Calendar getting these names from? Sometimes, I need to change the information. For example, a contact got married and changed her last name. Google calendar kept bringing up her former name linked to her email. I tried changing it everywhere I could think of, but her previous name kept appearing. It became rather uncomfortable. I appreciate your assistance with this.
If I just knew where Google calendar is getting the “Add guests” email list from, I could take it from there and make sure they are correct.

I started typing in Jane, expecting Jane NewName to appear. However Jane OldName came up.
