I just saw the "Ona" record. Up a few lines is Ivan with the same lower cased "v". The dates and places line up so this is very plausibly my great grandmother. I'm pretty sure I wouldn't have discovered that. Thanks so much!
I know you said Suwalki was hard to read. At least Google is giving me help with that, unlike the Rakutis side! Thanks again... exciting stuff, especially going through street view on some of these places and reading about their history!
