When requesting transfers please state your relation per find a grave guidelines within four generations (siblings, parents, grandparents, great-grandparents). Also, the goal is not to "own" every memorial of those to whom you are related. The ultimate goal is to have meaningful, accurate memorials that honor those who have passed away, regardless of who created the memorial or who maintains it.
The markers are there because those people lived not just because they died. Photos are a way of preserving the memories.
I really appreciate those who fill photo request. Those who live far away can see the photos of their loved ones marker.
