I saw this in an e-mail today, https://blog.billiongraves.com/2019/01/29/understanding-the-cemetery-symbols-on-your-ancestors-gravestones/. Part II should be posted next week. Some earlier links on the BillionGraves (BG) blog are https://blog.billiongraves.com/2013/08/20/headstone-symbolism-part-1/ and https://blog.billiongraves.com/2013/12/21/headstone-symbolism-part-2/.
I urge caution on headstone symbols as sometimes the person or family liked the symbol and it had little or nothing to do with the traditional symbolism associated with the symbol. I ran across this with an epitaph “God alone understands” and as I went around the cemetery, there were probably half dozen or more headstones with this epitaph. The headstones all appear to be from the same company, or at least they all had the same material and designs. In some cases, there was a reason for choosing the stone with the epitaph, but in other cases, it may have been cost motivated.
Here are a few other links about headstone symbolism:

The above sites include overlap. There may be cases where sites go with different observations on a symbol.
