The coordinates take you to stage 1 of a 4 stage virtual multi where you will get the numbers to fill in below for the coordinates to the final micro container. I noticed some large memorials in this cemetery. So, I am taking you what I think is the four largest. The coordinates for the other three are added as waypoints for you.
Final coordinates are at N39 AB.CDE W084 FG.HIJ
Stage 1 is unique especially considering how old it is. I am not sure when it was made, but they were both born over 150 years ago. (Look Inside).
A=How many people are buried here (MULTIPLY BY 2)
B=A.
Stage 2 is more colorful with a different type of memorial than stage 1.
C=2nd Letter of last name
D=1st Number of Day of month he passed
E=3rd digit of year she passed
Stage 3 is very high in the air with the last name really large and visible.
F=Juanita 3rd digit of year born.
G=Month Stanley was born.
Stage 4 like stage 1 looks like burial above ground with the parents born in the late 1800's.
H=4th digit of year Charles passed.
I=3rd digit of year Dora passed (MINUS) 4th digit of year Dora was born.
J=3rd digit of year Robert was born.
