The information that I have been able to gather on this family is as follows:
Father:Joseph (?) Izard, born 1816, France
Son: Louis Izard, born 1838, a native of Prumiere Hautes Alpes, France Wife:Josephine Barlier, born 1841, France
Louis may have had a brother, Jacques Izard, born in France Wife, Rose Rebecca Anfoux, born 1828 in Thibodeaux, La.
Isidore Izard, who is the son of Jacques and Rose and whom I believe may be the nephew of Louis Izard, is buried in the same cemetery plot as Louis is at Oakland Cemetery in Shreveport, Caddo Parish, Louisiana.
Another adult buried in that plot is Edmond Arnous, born 1852, Embrun, Hautes Alpes, France
I do not know if he is related to the Izard family.
