On March 16, 1871, Huff married the former Henrietta Burrell, a daughter of Jeremiah M. Burrell, President Judge of the Tenth Judicial District of Pennsylvania.
 They were the parents of eight children.

Along with sixty-odd wealthy Western Pennsylvanians including Andrew Carnegie, Andrew Mellon and Henry Clay Frick, Huff was a member of the elite South Fork Fishing and Hunting Club whose earthen dam at Lake Conemaugh failed on May 31, 1889, causing the Johnstown Flood.

He died in Washington, D.C. in 1912, aged 69.
 He was interred in St. Clair Cemetery in Greensburg, Pennsylvania.

Huff's Dupont Circle mansion, designed by Horace Trumbauer and Julian Abele and built in 1906, was sold by his widow in 1913 to the Argentine Ministry of Foreign Relations, and has since housed the Embassy of Argentina.
