Genealogy / Osolek, Russia (Poland) or damn you transcribers! [15]

So I have been trying to deep dive into my family tree. On both sides from my fathers line I have a very solid Polish line. But of course with everything going crazy post 1870 there is a lot to decompress and try to make sense of it all. One of those is my great-grandfather Alexander Paris.

So I have his naturalization document (ltparis.com/images/20170731-paris-nat.png) where he lists "Osolek, Russia" as his place of birth. But of course there is no such town as Osolek. The best that I can determine is that it could be Osiek. But these are all shots in the dark. I have a clearer picture of him just before coming over to the US. But I am just running into dead ends on finding more information.

Couple other oddities. First on his Naturalization and his WWI draft card he goes by Aleksander. Second on my grandfathers baptismal record the last name is non-Anglicized "Paryz". It's been debated for decades if the name had changed at some point. It's also debated that the name should really be Parecz. Search for both names in that time period does not come up with anything relevant this point.

So would love to hear suggestions. Ideas to look at. Here are the major points I know of him:

Alexander (Aleksander) Paris: 15OCT1874 - 24APR1926
My fraternal great-grandfather
Birthplace: Russia/Poland
- Listed as Poland in 1920 census
