Davenport: Homer Davenport went to the desert in 1906 and returned with 27 horses. In the mid-20th Century, breeders were able to locate 18 horses in North America that traced exclusively to 14 of the original imports. These are called the “second foundation:” mares Dhalana, Dharanah, Dharebah, Dhanad, Saranah, Sahabet, Tara, Asara, Ehwat-Ansarlah, Antan, and Maedae and stallions Tripoli, El Alamein, Dharantez, Nahas, Abu Hanad, Kamil Ibn Salan, and Ralf. Contemporary horses called “Davenport Arabians” trace exclusively to theses imports (*Abeyah, *Abbeian, *Deyr, *Farha, *Gomusa, *Hadba, *Haffia, *Haleb, *Hamrah, *Jedah, *Muson, *Reshan, *Obeyran *Urfah,*Wadduda, and *Werdi) and, in some instances, in possible combination with pedigree elements from the Hamidie Society importation of 1893 to the US.

During the 1990s, Dr. Ann Bowling of the University of California at Davis conducted a broad survey of mitochondrial DNA (mtDNA) in Arabian horses. This genetic material is passed from mother to daughter and has proven to be a reliable indicator of matrilineal descent. Dr. Bowling’s study suggested that the identity of the mares Saleefy and Freda were inadvertently switched after 1918 when the mares were shipped by rail from Hingham Stock Farm in Massachusetts to the Diamond Bar Ranch in California. At that time, they were both mature bay mares with minimal white markings. If this switch did occur, then Schilla (registered as a daughter of Saleefy) was actually a daughter of Freda (descended from the the Hamidie horses *Obeyran, *Mannaky, and *Galfia), and these Hamidie horses would be added to the list of foundation horses given above.
