Comte de Sainte Croix

A comte de Sainte-Croix named once, on 1874-06-12 (020.0225): «Depuis son histoire avec Gambetta je voudrais voir le comte de Sainte-Croix.» The Mon Journal t.3 index has «Sainte-Croix (comte de), 230». Marie wants to see him because of a well-known quarrel with the republican leader #Gambetta, which was in the news that month.

Identity uncertain

We are not sure who this is. A June 1874 engraving in the Illustrated London News describes «M. de Saint-Croix» assaulting Gambetta at the Gare Saint-Lazare in Paris when the crowd heckled him, so that is very probably the «histoire» Marie means (Mary Evans Picture Library, «Paris unrest», https://www.maryevans.com/history/paris-unrest-10204560). That source does not give his first name or say he was a count, and none of the sources found says who he was. If you can identify this person, we would be glad to hear from you.
