As a follow-up from my post this morning, below is an advertisement for Raphael Tudury's Orleans Syrup and Cordial Manufactory located at 147-149 Elysian Fields Street. This is where Joseph Halter worked during the 1860s and 1870s in New Orleans.
This puts a different view on the movement of Joseph Halter between New Orleans and Evansville after the Civil War. Perhaps he was accompanying shipments of syrup and cordials from New Orleans to Evansville. I'll have to look for this in the Evansville newspapers.
In any case it is a cool find - another member of the family involved in the liquor business.
