Skowronek ("Skylark"), foaled in 1909, was bred by Count Potocki at Antoniny Stud in Poland.
His sire Ibrahim was imported to Poland from Constantinople, Turkey in 1907 as an 'Original Arab'. His dam Jaskolka (Yaskoulka) ("Swallow") was of established Polish bloodlines. Skowronek was a beautiful homozygous grey, snow white in his maturity. He was imported into England in 1913 by Walter Winans, was sold to Mr. Webb-Ware, and then to Mr H. V. Musgrave Clark, from whom Lady Wentworth subsequently acquired him.

Just how influential has Skowronek been in the breeding programs in the US and Canada? Let's have some fun with statistics.

As of January 1, 1998, my personal data base contains 32,367 USA and/or Canadian registered Arabians. 10,732 of these horses are descended from Skowronek one or more times. This does not give us a reliable picture though, since I've done exhaustive research on Egyptian Arabians for my books. 16,194, or about half, of the horses in my data base are straight or pure Egyptians, and Skowronek has had practically no influence in Egyptian breeding programs, with only one son, Registan, in Egypt. Only 43 of the 16,194 Egyptian horses in this country are descended from Skowronek.

If we discount the Egyptians, we have 16,173 non-Egyptian horses, out of which 10,689 are descended from Skowronek. This count is still biased, as I've also done exhaustive research into Spanish Arabians for the books.
I have 2,095 USA and/or Canadian registered Spanish Arabians, out of which 494 are imports. BUT!!! 2,062 of these are descended from Skowronek, which leaves only 33 without Skowronek blood. 31 of those 33 were imported, which leaves us with a whopping 2 (count 'em, ONE, TWO) straight Spanish Arabians bred in the US that are not descended from Skowronek. All of the later imports in this group are descended from one or more of the mares belonging to the Duke of Veragua. We know nothing about the breeding of these mares, except that the Duke bred only purebred Arabians and of mostly Crabbet bloodlines. Therefore, we can not assume that we don't have some more Skowronek blood running around in these horses. That leaves us with only the Draper and Steen importations and one horse bred in this country from the Draper imports that we know have no Skowronek blood. 17 horses from 2,095 pure Spanish! I think we can safely say that Skowronek has been EXTREMELY influential in the Spanish breeding programs.

Let's leave the Spanish horses off too and see what is left. We have 14,078 horses that are not pure Egyptian or pure Spanish, 540 of which are Sheykh Obeyd and 406 of which are Babson + Turfa, which leaves us with 13,132 horses, out of which 8,627 are descendants of Skowronek.
This should give us a fair cross section of the Arabian population in general, as I've subtracted all the major breeding groups I've been doing research on. The remaining horses are a mix of English, Polish, Russian, Desertbred, part Spanish, part Egyptian; whatever I have come across as I've been doing pedigree research. I've done a bit of 'all get/progeny' of some horses, but it has been scattered, some with and some without Skowronek blood, and in any case not more than one or two generations, so should have no major influence. So, what we end up with is that about two thirds of these 'All American' Arabians have Skowronek blood.

Out of the 465 pure Polish horses in my data base 156 have Skowronek blood. Out of the 143 pure Russian (other than pure Polish) horses 122 have Skowronek blood. Again, this is only counting horses registered in the US and Canada.

Yes, Skowronek may be almost a century old, but he is here to stay!

Aren't computers fun?
