Hi Dana, I found on ancestry.com that Edward Cohea was in the military in 1848, during the Mexican war and was in the infantry, no other info was provided. I also found his parents and was able to take his family back to the 1700's.
Edward Cohea married Geraldine Eliza Pell 1851. In 1864/65 he was a conductor and in 1867 he work in a liquor saloon. If you don't have the Cohea family tree, i can email you the info.
