Does this last name sound any Polish to you: Renzhiglo? I have an online sourse in Ukrainian saying that it is Polish. The sourse, however, says nothing about the origins. I also know that it comes from Ukraine.
It doesn't to me, but it may mean nothing. I looked via Google for "Renżyglo" --"Your search - renżyglo - did not match any documents.", "Rężyglo"--"No results found for rężyglo", and "Renżiglo"--"No results found for renżiglo", "Renżygło"--"Your search - renżygło - did not match any documents.".
I have, however, found something related to "Rężygło" on what looks to be Ukrainian websites.
