I just wanted to let you know that a memorial manager cannot delete a photo added by another person, it can only be deleted by the person who posted it.
That said, please do not delete that photo from her memorial. Not only does it show the stone at a different time, but it is a much closer shot that shows what the stone says. That is a very worthwhile photo to have on the memorial.
Find A Grave Memorial# 64984581 Your photo on Find A Grave Memorial# 64984581 does not match her death date. It is similar to the photo I took for Katherina's grandmother Find A Grave Memorial# 64984601. Katherina was never married and the "wife of" at age 16 seems confusing.
