Can anyone help me with the Wartburg Orphange/Home/Farm School located in Mt. Vernon/Yonkers NY.?

The surname I am researching is Arfmann. The children were named, Elmer, Arthur, Henry and Mable who I believe were in this home between 1910-1920.

Is anyone familiar with this home and is there a means of obtaining a list of names of individuals that were residents here during that period?
