Sorry Hansi, must take issue with you on this one. There was most certainly a strain (female spelling) which in full is correctly written as Keheilet Ajuz of Ibn Rodan. And there most certainly was a breeder named Ibn Rodan. This is very well documented. Over the years, as with many strain names, the full strain name has been shortened to Keheileh Rodanieh (male: Keheilan Rodan). The most famous mare of this strain was Rodania (named for her breeder/strain, she was bred by the Bedouin tribesman named Ibn Rodan of the Roala tribe who 'owned' this strain which is named after his family). There are other horses of this strain in other early western stud books (eg French) but I believe Rodania's is the only tail female line that has bred on to modern times. It is a very large family world-wide as Rodania had 3 famous daughters - Rose of Jericho later exported to Australia, Rose of Sharon later exported to USA & Rosemary who stayed in GB- who between them had many daughters and the family has spread all over the world over the centuries.
To quote from Peter Upton: Rodania was born circa 1869, she was bred by Ibn Rodan of the Roala tribe and taken in war from their Sheihk Sotamm Ibn Shaalan, in 1880, by Tais Ibn Sharban of the Gomussa. An old and celebrated mare, formerly the property of Beneyeh Ibn Shaalan, and the cause of a feud between him and his kinsman Sotamm. Purchased by the Blunts from her owner Tais Ibn Sharban on 12 April 1881, in the desert, near the wells of Abu Fayal, for £124. Chestnut, with near hind foot white to above fetlock, blaze to mouth, pink on upper lip, deep jowl, eyes showing white like human eyes, splendid shoulder, extraordinary strength. Wounded on the quarter, belly and chest, probably sustained in a ghazu. A somewhat uncertain temper. 14.2 hh. Imported to GB in 1881. She became sick and was put down in the winter of 1889/90.
To quote from Lady Anne Blunt: 'We had heard of this mare 2 years before we saw her on our journey through Nefud to Nejd beyond Joff in January 1879 at the well of Shaqig, where we met a son of Beneyeh Ibn Shaalan. We were told about the quarrel between Beneyeh and his cousin Sotamm Ibn Shaalan, on account of this chestnut mare which Sotamm insisted on having and managed to take by force, failing to get her by fair means. Beneyeh then had left Sotamm to fight his own battles with the Sebaa, in the course of which, last summer, Sotamm lost the mare for whose possession he had sacrificed a valuable alliance, who was taken from him by Ta'is Ibn Sharban of the Gomussa in 1880. She strikes with her forefeet and kicks too. Her strange temper may possibly be the result of having been knocked about and especially the severe firing she had undergone.'
I hope this clarifies things a little.
