Hi Amy, There has been messages just posted to the Infoukes.com mail list - re the given name Wasy. Vasyl and the English variation of same.
Thought the name васыл
translates to Basil in English - many families use the name William -[Bill] a diminuative of same ]
Others use the name Charles but here in Canada - William/Bill is most often used.
If you look at the Ukrainian Alphabet - there are sites online that will show the alphabet in crylic as well English
Have you searched Latter Day Saints - to see if they have transcribed information from Parish records in Ukraine or wherever the family is from.
Cheers, Stella
