Nenagladny Perchino was first bought by Joseph B. Thomas, Valley Farm USA from the Grand Duke Nikolai Nikolaewitch.In US he was renamed Nenagladni of Perchina. He was later sold to Mr Auguste Caron, kennel de l'Etoile in France. Nenagladnys name can be traced in many pedigrees in Great Britain through the french import Narcisse that went to Mrs Vlastos Addlestone kennel, Canada (through British import Kuban's Kuzma), and later on to Sweden (through US Imp. Tiercel of Phantom Lake) and then several other countries.
from Borzoi Past group, Sue E.A. Vasick: <<American Ch. Nenagladni of Perchina was born February 8, 1903 at the Perchino kennels of Grand Duke Nikolay Nikolaevich in Russia. Known as Nenagladni Perchino in Russia, he was purchased by Joseph Thomas of Valley Farm kennel and taken to America where he was registered as Nenagladni of Perchina, the name for which he is known. He was a white dog with sparse tan markings, sired by Armavir Perchino out of Podruska Perchino. He sired at least seven litters for O’Valley Farm and a couple of outside litters as well, and was then sent to France where his son, Mazeppa de l'Etoile, carried on his bloodline. Here in the States, possibly his son Viouga O'Valley Farm was the most prolific.
