Henry / Daigle Roots, Baton Rouge Louisiana

Who was Isidor Henry?  He married Arthemise Daigle in Baton Rouge in 1841.  They had a few children but I believe only our Theodule survived.  Arthemise can be traced back but I can't verify parents for Isidor.  I've seen names posted online but unsourced.  Isidor is one of my missing links.
