'Fraid not, sorry.
The CWGC stone in the photo below (Jefferson) is Section 10, Lair 560 and it's the closest I can find to Lair 598.
There's no quick way to find a specific lair - you really just have to check each stone for a number and try to figure out which way the lairs run.
You are looking for Lair 598, so if you start at Francis Jefferson's stone, the lair you're looking for will be 38 lairs away. (This could be in the same row, the row behind or the row facing depending on the numbering system)
Each Lair is 3 feet wide, so an option is to take a tape measure and make measurements in increments of three feet, or take something with you which you had pre-measured.
Of course you could go along and there's a stone there with the names you are looking for!!
