WAHO accepted progeny of 30 Maria xx as purebred Arabian.
Exp. to Austria 1852 and stood at Piber Stud; 1853 transferred to new established state stud Kisbèr in Hungary.

According to the 1972 Babolna stud book, the first edition of volume I of the Polish Arabian Stud Book, and Dr. Walter Hecker’s history of Babolna, the Austro-Hungarian broodmare 30-Maria was an English Thoroughbred foaled in 1842. Maria’s registration as a Thoroughbred and her foals born in England appear in Weatherby’s General Stud Book, which states, “Sold to the Austrian Government in 1852, before foaling” (see volume VII, page 230).

She was left in England to foal and then brought to the Austrian stud of Piber later in 1852. The Austro-Hungarian government established the stud farm of Kisber in 1853 for breeding Thoroughbreds and Thoroughbred crosses, and 30-Maria was sold to Kisber in 1854. On May 3, 1861, she was bred to the imported desert bred stallion Aghil Aga, producing a bay filly on April 7, 1862. The filly was designated 3 Aghil Aga when she entered the broodmare band at Babolna, and the 30-Maria line descends through her.

30-Maria herself was transferred from Kisber to Mezoehegyes in October of 1862. Her last owner was Baron Bela Wenckheim; 30-Maria died in 1865.

The broodmare daughters of 3 Aghil Aga included 6 Mahmoud Mirza (1870), 35 Mahmoud Mirza (1871), and 90 Mehemed Ali (1878), but it was through 6 Mahmoud Mirza that Babolna developed a long line of horses with Arabian blood plus 30-Maria. A more recent example of such breeding is 30-Maria‘s tail-female descendant 125 Ghalion, born in 1975. After 12 generations of crossing to Arabian stallions, 125 Ghalion has just 0.024% of 30-Maria‘s blood.
