I believe the relic is soil from the catacombs in Rome; "Terra delle catacombe" means "earth from the catacombs." Very cool!
Well, I should have realized that. I just didn't make the connection with the word Terra.
There is a floor cabinet near a side Chapel in my Parish where people place items free for the taking. Many times it will be items from a deceased family member and I believe this is probably the case with this Rosary. There was a well-worn brown scapular and some old prayer cards there with it.
Anyhow I took the rosary to the two reliquaries under the side altars and touched the crucifix to them. They are the skeletal remains St Bonosa ant St Magnus. Both said to have been martyred in the third century and originally buried in the catacombs.
Here is the info the parish offers of how they made it to Kentucky.

I often visit the reliquaries of both and pray for their intercession for an increase in faith at a level approaching their's and the past few months I've been doing so more frequently. Now I'm wondering if there is a connection between me being the one to claim the Rosary and my first thought after seeing the word catacombs on the crucifix, which was to touch it the the reliquaries.
Coincidence or Devine guidence, not certain. But I feel blessed either way !
