I'm sorry but I don't have time to make changes to memorials. I'd be happy to transfer management to you if you email me your Find-A-Grave ID# and the names of the memorials you'd like to change.
In the past and when I have time, I like to take extra pictures of tombstones that aren't necessarily my own ancestors and add them to the site as a service for others. My goal isn't to create a family history - just provide the tombstone photos for people. Again, I'm more than happy to transfer management of any of the memorials that I've created.
