The given coordinates will take you to the grave of Jacob's 11-year-old son. Use information on the tombstone to determine the values of A through F. Then ADD .ABC to the given latitude and SUBTRACT .DEF from the given longitude.
A=the # of letters in the 1st 3 lines of Jacob's son's gravemarker, minus the # of letters in Jacob's last name (careful here!)
B=the # of letters in the last word on the tombstone
C=the 2nd digit of the day Jacob's son died
D=the # of letters in the 1st line minus the # of letters in the 3rd line
E=the # of words on the 12th line (careful here, too: context is everything!) minus the # of words on the 18th line
F=the # of letters in the last word on line 15
Checksums for both ABC and DEF are 7.
There are interesting gravestones in this country churchyard. I especially invite you to find the memorial to Horace Kenneth Greenwood, Staff Sergeant, USAAC, WWII, who lost his life over Regensburg, Germany, on February 25, 1944, and who is interred in Zachary Taylor National Cemetery in Louisville, KY. Please be respectful as you gather the info you need to find the second stage and as you visit the graves.
