How to I stop getting my whole family's photos on my iphone?

Apple IDs should not be shared. Each person should have their own Apple ID.

If you are still getting your family's photos, then it means you have not actually signed out of the Apple ID entirely. Probably you signed out of the iTunes and app Stroes, but not out of iCloud.

Make sure iCloud has been singed out of the shared Apple ID in Settings->Account(top of settings).

Scroll down to the bottom of the page to find the Sign out option. Then sign in with your own Apple ID.

No. No shared albums. We were sharing an apple ID, but I created my own and logged in but am still getting all the photos.

It sounds like somewhere along the way, that older ID is still being shared. Are you certain you created a new ID?

Then the Photos are no longer shared. When you signed out, it should have asked you if you wanted to preserve the iCloud content on your iPhone, you would have needed to answer "no" then to have all the shared photos removed.

As it stands now, you would have to manually delete them from the iPhone if you no longer want them. If you correctly signed out of iCloud, there is no longer any connection to the Family Album.

Are they sharing photos with you through a shared album -- How to share albums in Photos on your iPhone, iPad, and Mac - Apple Support?
