I might be reading this wrong; but in most cases, a John/Jane Doe are “unknown” people or they would be listed under their real name & returned to their family for burial. The true “unknown” deceased are buried in a potters field where they don’t get a headstone…they get a grave marker with a number. That number correlates back to their case file. In a rare case where the family is located after burial, they may retrieve the deceased & bury them wherever the family designates at the family’s expense.
With the current trend of cremation acceptance, I feel that would start the trend of cremating the “unknown” en masse but NOT giving them their own urn. Even the kind hearted people don’t care what happens to the unknown & the rich won’t allow it to happen to their family. So, I’m going to guess that there is NO personal headstone nor urn.
I may have read more into this than necessary, but that is my way of thinking!!!
Now if a “known” person actually had the name of John/Jane Doe, they would be turned over to their family for burial or cremation & then it would be a personal arrangement where a headstone or personal urn would be used.
I’ve only ever heard of 1 person whose name is John Doe & his real name is John N. Duchac & he’s an actor, singer, songwriter, & co-founder of the LA punk band X. He also has ties to movies The Bodyguard (1992), Road House (1989), & Ten Inch Hero (2007). Since he is known & only uses the stage name John Doe, I’m going to assume that he has relatives or has people who would arrange for his funeral, so a potters field not required with this own personally chosen headstone or urn.
