Almahmoud's dam was Arbitrator, a daughter of the 1934 Belmont Stakes winner, Peace Chance. She was sired by 1936 Epsom Derby winner Mahmoud who was imported to the United States in 1940 by Cornelius Vanderbilt Whitney. Almahmoud won important races at age two and three before being retired to broodmare duty. Through her daughter Natalma, Almahmoud became the maternal grandmother of Northern Dancer whom the National Thoroughbred Racing Association and others have called "one of the most influential sires in Thoroughbred history"  and is regarded as the 20th century's best sire of sires. 
Another daughter of Almahmoud, Cosmah was the 1974 Kentucky Broodmare of the Year who produced Halo who in turn sired Kentucky Derby winner Sunny's Halo and U.S. Racing Hall of Fame inductee, Sunday Silence. As well, Cosmah produced Queen Sucree, the dam of Kentucky Derby winner Cannonade.
