Question about The Good, The Bad and The Ugly (ignore this-->)?

I need this explained to me, I missed this part somehow.
The money is buried in the UNKNOWN grave, and Blondie knows it. If Bill Carson told Blondie the name of the grave that the money was in, how did he know that the name Arch Stanton would be in the cemetery. Did Bill Carson tell him about both the Unknown and Arch Stanton graves?

The gold is buried in the unmarked grave next to Arch Stanton's. As there are many unmarked graves, it only makes sense that Bill Carson used Arch Stanton's grave as a point of reference, and Blondie put together an easy lie.
