The surname Joryn is spelled ????? in Russian databases.Denis (son of Wasyl) Joryn is the only one I found in Ukraine. The Ukrainian transliteration would be ???i? and I found nothing whatsoever using the Ukrainian Cyrillic Alphabet.
Consider contacting Andryj Dorosh, a Volodymir-Volynskij resident and genealogy researcher, who has a reputation for ferreting out information not readily available.He is quite familiar w/Lutsk Archives and is knowledgeable re Vohlyn region, both old and new.If anyone can come up w/some answers for you, he is the one.He is very tenacious and his rates are very reasonable. I recommend him highly. http://west-ukraine-tours.com/index/about_me/0-7http://west-ukraine-tours.com/index/about_me/0-7
