Rank Of Leticia's Ancestors

Hi, Leticia,
 
My husband was in the U. S. Marines, and he said that rank insignia are universal.  He says the man sitting in the chair is a Captain (capitan).  The other man with the blue eyes and a badge on his chest and insignia on his collar (it looks like an eagle-emblem), is a Major (mayor?).  The rank above major is Lt. Colonel.
