At the posted cords you will need to look for a Headstone that has the names of Alexander @ Isabel on it.
There is an inscription at the bottom of the stone. It comes from a Poem AE FOND KISS and then turned into a Song. After doing some research on the poem I can see why Alexander had it put on the Stone. Take time and read the full poem.
From the inscription you will need to count cerrtain # of letters to find the final at
N 40 .31.ABC W 78 22.DEF
# of F's = A
# of T's + W's = B
# of K's = C
# of C's = D
# of L's = E
# of N's = F
This is located in a Geocache Friendly Cemetery and no night caching.
