"Stanley and Harris Not on the Titanic: Roebling Chauffeur Took Earlier Boat-and Other Local News from the Wreck" 
"Word was received by Charles G. Roebling yesterday afternoon that Frank Stanley, the chauffeur who motored Mr. Roebling's son, Washington A.Roebling II, and Stephen W. Blackwell through Europe, that he was not a passenger on the doomed Titanic but was safe in New York. Stanley saw his name on the list of those thought to have perished and immediately wired the Roeblings to the contrary." 
The article relates that Stanley had fallen ill while in Europe and received permission to depart early. The Times article specifically states, "Stanley arrived in New York from Rotterdam the later part of last week."
