With all of the free time I've had lately, I wanted to look into learning more about where my family comes from as that's been an off-and-on project for multiple years. Learning that I have great great grandparents (vj24's great grandparents) are buried in this cemetery, I decided to put a short multi out here.
The posted coords will take you to a gravestone with the last name De Boer. First names start with R and F because there are other De Boer family members buried nearby.
Your final coordinates should be N42 50.ABC W085 56.DEF
For ABC use the name on the left. For DEF use the name on the right
A= Second digit of the birth year
B= Last digit of death year minus the first digit
C= Third digit of death year minus 1
D= Number of letters in between the years
E= Second digit of birth year
F= Third digit of death year
Checksum= 37
