This symbol has a few accepted meanings. A heavenly welcome, an earthly farewell, simple unity, or friendship.
If you look a little more closely, you will notice the sleeve attached to one hand is feminine, and the sleeve attached to the other hand is masculine. These hands, carved in this way, symbolize holy matrimony.
I have seen the clasped hands symbol fairly often when perusing tombstones. Often enough, that I have gotten a little "used to it." I looked at this particular stone several times while at the cemetery, and I have looked at the photos I took several times more. Only when I enlarged the clasped hands image did I notice one was feminine and one was masculine. When researching tombstones, details do matter. This particular stone was easy to read. The next one might not be. Every little clue counts!
