How I found Henry's Name

The mystery of H. Wallace Gale's name was a tough nut to crack at first since all of his records referred to him as H. Wallace Gale.  Even his cenotaph (with an error in his death age - should be 20 years old and not 21 years old) referred to him as H. Wallace Gale.  For some reason, it was important for H. Wallace Gale to use his middle name more than his first but he included the initial to his first name always.  This made him unique.  He was referred to as H. Wallace.  It took me a while to find out what the H stood for, but with the help of the National Park Service, I was able to find out his name was Henry.   Here are the screenshots from their website, that helped me crack the mystery.
