Hello.....my great great Grandfather was John Delesse who immigrated in 1847 from Hombourg-Haut, Lorraine France.. He was born in Hombourg-Haut, Lorraine France in 1819, and married there in 1845. After immigrating he settled .in Missouri where he died in 1902. His obituary indicated that he had served 7 years in the French army. Using age 18 as the date of his start of service would place his dates of service of 1837 to 1845. What does one need to know to find his military records and where would they be found? Thanks for the help. Ray
