It occurred to me that my previous post could be helpful in yet another situation.
Due to migrations of late 19th - early 20th century, families were split along both sides of Atlantic Ocean.
As the result many of the Russian Immigrants of the 1980s could recall the legend of a relative who left to New Word.
Thus Ellis Island could be the first step to find these long lost cousins and reunite the families.
Please refer to my post
My ancestor came from Russia but the place has been forgotten
for search advice.
