it's funny you mention that
I found a 1930 census report (name pronounced Zinkavice this time.
All names and dates are correct yey on this report my great grandparent state they were born in lithuania and immagration date was 1890.
so it fits
i guess the borders were changing here in america too.
There was probably a reason for this like you said, and i've seen on some of these census report, they lumped Russia, polish, lithuanian and others all as Russian or Russian/Poles.
Could have been they way they catagorized maybe.
At least, at this point, I'm 99% sure my heritage is Lithuanian.
You don't live in Russia (if that's were they lived) and speak the Lithuanian language if your Russian.
So that sealed it for me.
Nothing against the Russian heritage but I'm happy to still be Lithuanian confirmed.
As i'm rehabinf from shoulder surgery, I still have some free time to continue this research.
Thanks for all your help!
