Good afternoon emailnameissue,
Welcome to the Apple Support Communities!
I understand you are trying to send an email from the iCloud website but the "From" field is showing your husband's name. If you are sharing the same Apple ID this will certainly be an issue. If you are not using the same Apple ID, or have recently created your own Apple ID, try this:
- Log on to the iCloud website with your own Apple ID and password
- Open the Mail app
- Click the icon to compose a new email message
- Click on the name or email address that appears in the "From" field
- If there is more than one option, you should see a drop-down arrow beside the email address in the "From" field.
- Click on the drop-down arrow and choose a different email address.
You can also check the Preferences for the iCloud email account:
- Click the icon that looks like a gear or cogwheel in the lower-left corner of the Mail window
- Click the Composing tab
- In the "Send From" section, beside the "Set a default address", click the down arrow and choose the email address you prefer.
- Click Done
Be sure to sign out of the online iCloud account when you are done using it.
