I know these forums get these kinds of questions a lot (and I actually found a post on here asking about Terlesky from over 10 years ago, eek), but this one is actually slightly different in nature, and hopefully can be answered by anyone who speaks Ukrainian (or possibly Russian or even Polish).
First, my actual ancestors: as far back as I can trace, my great-great-grandfather was Eli Terlesky (Terlesce), his wife Mary/Maria Karpuik. They were from Ludi Horecei in Bucovina, near Chernivtsi, and moved to Buchanan, Saskatchewan in 1901. They had Nick, Steve, John, Dora, Harry, and Polly. John had Nettie, Bella, Peter, Mary, Dora, Rose, John, and Victoria (phew). And so on until me.
Okay! So, unless you can help at all with any of that (which would be swell) I'm trying to figure out what Terlesky actually *means*. Names have meaning, of course, for example Toma ultimately just derives from the same source as Thomas, which was the Greek form of the Aramaic ta'oma', twin. Exciting stuff. I actually love word origins, and it was my efforts in tracing Terlesky that led me into the big scary world of genealogy.
But this is really hard for foreign surnames, especially ones that were altered so frequently by misspellings and phonetic approximations, even moreso for one that is, as far as I can tell, relatively uncommon.
I know the -sky suffix is common in Slavic names, and is used at the end of the full form of possessive adjectives (perhaps along the lines of "of"). Or! It's used like the "-er" in English to demonstrate the doer of an action. I don't know! I don't speak any Slavic languages. Maybe hopefully you do?
I'm wondering if there are any Ukrainian (or northern Slavic) words similar to "terle" (or terl or terles). Given the different forms of the name over the years, I'm thinking it was at one point Terletsky, so there may even be a word/name/place similar to "terlet." Again I don't know any Ukrainian (or Russian, or Polish), but if you do could you help me out?
