** The cache is not at the given coordinates**
I got the the idea for this mystery cache after reading an interesting book (I'm not going to make the puzzle too easy by giving you the title of the book, but it should be an easier puzzle to solve than my first mystery cache). To work out the real coordinates for the cache you will need to do some internet research and then make some calculations to work out the final coordinates. If you're not sure where to start check the hints below, although the puzzle should be able to be solved without them.
The cache is a nondescript 2L sistema container with logbook, pen, and various trinkets. The pen has not been tested (it is in an unopened packet) so it may pay to bring your own writing implement just in case.
Cache is at S40 AB.CDE E17U VW.XYZ
where:
A = number of letters in first name

D = (last digit of year that vandals broke into the storage facility) plus (number of children times 2)
E = last digit of year body returned and burial planned
U = last digit of height
V = last digit of year of death
W = first digit of age at death
X = third digit of year of birth
Y = number of letters in surname of professor who embalmed the bodies
Z = (last digit of year mummy was stolen) minus (number of letters of surname of spouse)
