I’m hoping the collective knowledge of the internet can help with this, I had a lady call me up about these mill stones in her back yard – two are complete and I dug into this pile of stones near the fence and started finding pieces of others. She’s wondering where they might have come from. One person told her they came from somewhere in Utah named after a President, maybe Fillmore. She in a home built in 1960 in Sandy, Utah and the stones along with the stone work all over the house is from the original owner who already gave away some of the millstones.
