A Hidden Gem Mystery Cache

While out on our travels we happened up a cemetery that we have never seen before.  Been by here before, a few times actually and never seen this till today.  So a puzzle had to be made. Format is: N 35 09.ABC W 085 47.DEF!

While out looking for a cache we came across an old cemetery that we have never seen before.  We love old cemeteries and have to get more information about this one but need to bring other people here to see it first.  Good luck with the puzzle, shouldn't be too hard.

A.The date added together that Patrick Henry Jones was born?  number + number=A

BC. The date that the Infant DAU of JW & ME Jones was born and subtract 8?  Jan BC, 1905

D. Subtract 1835 from the year Norcissa A. Alexander was born = D?

E.  Multiply the total number of rocks in the cairn by 0 and add 8?

F. The last number of the year that Christian Klipper departed this life and subtract 2? E=183F

Good luck and post if you have more information about this cemetery.
