As someone who knows a little about memorials I can speak to the subject. Churches are built by memorials, whether it is for the altar, the pulpit, the organ, or the stained glass windows. When we built our present church I made it a policy to have a memorial plaque in the narthex rather than on the objects. No one was upset by this at all. When we wanted to make a change to one of the memorials nothing changed because the memorial was still on the plaque. When the name is on the object itself it takes on a special and, if you will, a spiritual meaning because the object becomes a visible reminder of the person memorialized. Most of the time folks just want some special acknowledgment of the deceased family member or friend. Recognizing that goes a long way in satisfying that need. Removing a tree in memory of someone generally will not be taken well because there is nothing physical as a reminder. We all have special objects that are dear to us because they remind us of someone special. I have my Dad's Bible. Whenever I pass it I am reminded of my Dad and his faith. Clubs just need to be sensitive to people's feelings.
