The above co-ordinates are for St Michael's Catholic Church in Douglas. Behind the church you will find St Michael's Cemetery. Once you have entered the cemetery you will need to look for the largest/tallest monument. This should not cause any confusion as one clearly dominates all the others. On this monument you will find a dedication to Michael Byrne. You will need to gather some information about Mr Byrne to determine the cache location.
Cache is located at N 45° 3A.BCD W 076° 5C.CCE
A = number of Byrne's wives listed on monument
B = the third digit in the year he passed away

D = digtal root of the year he was in when he passed away
E = digital root of his hometown
The digital root of these five digits is 3.
