Denis Gage Deane-Tanner

Denis Gage Deane-Tanner (born 14 September 1876 - ???) was the brother of William Desmond Taylor and nephew of Charles Kearns Deane Tanner.

Denis Gage Deane-Tanner was the fourth of five children born to Jane O'Brien (of Carlow, Ireland) and British Army Major Thomas Kearns Deane-Tanner (of Cork, Ireland) in what is now Carlow, Ireland. Denis was raised at the family home, Straw Hall, until he attended school at Pooles House, Clifton College in England. His father was a lifelong military man, who also started the Volunteer Fire Brigade in Carlow. Denis had two uncles via his father, both were Doctors. Uncle Lombard worked at both the Charity Hospital and St. Kevins hospital in Cork. Charles Kearns Deane Tanner, an Irish surgeon and politician was Denis' other uncle. Uncle Charles was deeply involved in Home Rule politics, eventually leaving medicine to concentrate solely on his interest in the Irish Home Rule cause.

Tanner was a lieutenant in the King's Own (Royal Lancaster Regiment) of the British Army during the Second Boer War, during which time he was awarded both the King's and Queen's medals for service in what is now South Africa.

After leaving the military, he traveled to New York City to join his elder brother William Cunningham, arriving in 1903. Denis followed his brother Williams example and went into the antique business, working at The Antique Shop on Fifth Avenue and A.J. Crawfords also on Fifth. Denis met his future wife Ada in New York City. Ada was from a long established family, the Ketchums of Buffalo New York who helped establish the Buffalo and Erie area of New York before the Revolutionary War. Denis and Ada Charlton Brennan wed September 14, 1907 in New York City; the couple would have three children, daughter Muriel Denise (born August 1908), son Kearns (born August 1909) who died within hours of his birth and lastly, daughter Alice Eleanor (born December 1910).
