Intrigued by a paragraph in Stauffer Genealogy of America by Ezra N. Stauffer, I searched further for Isaac Stauffer, who Ezra claims to have been a millionaire cotton merchant.
I think that this Isaac Stauffer (1) is the father of Isaac (2) Hull Stauffer who owned Stauffer Eshleman & Co. in New Orleans. Now the search begins for his ancestry. An interesting document about Isaac's (1) daughter can be found at www.neworleansbar.org/documents/ENews06Nostalgia503LostAn.doc
A recent Google search using 3 "garden lane" stauffer new orleans revealed evidence that Isaac Stauffer once owned the mansion at 3 Garden Lane in New Orleans (Maestri, R.). This is located adjacent to the New Orleans Country Club.
I am still searching for photo evidence of any Hurricane Katrina damages to the property.
Google Maps Satellite images have good close ups of the area.
3 Garden Lane, New Orleans
