Genealogyanon here.
First, don't call my frenz stupid.
Second, historically, we have had immigration questions on the US Census, such as year immigrated and citizenship. A legal, naturalized person would have Na in that column.
Next, 400 years have passed with immigrants coming here, documented. The Q at hand is that many MILLIONS of people are here illegally and cannot vote. If House representation is by population, only citizens should count.
An aside, except that MZ family has older Russian ties, I see nothing unusual. German, Austrian, Poland, Russia all to Brooklyn Jewish neighborhood
