Denis Gage Deane-Tanner

Denis was raised at the family home, Straw Hall, until he attended school at Pooles House, Clifton College in England.

Ada who had contracted tuberculosis (presumably from Denis, as he and many of his close and distant relatives had the disease) was periodically treated for the illness throughout her life.

On 25 August 1912 (his daughter Muriel's fourth birthday), after visiting Ada in the Edward Livingston Trudeau Sanatorium in Saranac Lake, New York, where she was receiving tuberculosis treatment, Denis, as his brother did several years before him, disappeared from his family and all known friends and acquaintances.

Eventually Ada established contact with Denis' brother, esteemed Hollywood director William Desmond Taylor.

[1] It is believed that Denis eventually moved to Los Angeles, California and resumed contact with and quietly worked for his brother for a few years.

The rumor that the blacksmith in Taylor's 1914 film Captain Alvarez was Denis Deane-Tanner was mentioned in the papers and attributed to an anonymous New Yorker who stated he recognized him.
