Names ending in -sky or the feminine form -skaya are often
based on places of origin. A classic Russian example would
be Aleksandr Nevsky, the knight who acquired his last name
by defeating the Swedes in the year 1240 on the Neva River.
Just as French has family names de (place name), German has
von (place name) and Dutch has van (place name), so Russian
has (place name)-sky.
According to Wikipedia there is a town in Ukraine called Kalinov
in the Sumska region in northeastern Ukraine and in Russia proper
there are Kalinovs in six different regions. However because most
Russian Jews were Polish Jews who found themselves in the Ukraine
after the Tsars progressively dismembered eastern Poland, chances
are pretty good that Alexander had an ancestor >from Kalinov, Ukraine.
This could have happened long, long ago but it might not have been
so long ago if someone elected to change a conspicuously Jewish name
into something more "Russian". It could well have happened when the
ancestor moved to Kiev, or it may have happened at the point in time
that someone saw the liberating potential of becoming russified after
feeling cooped up in a Polish ghetto. The Polish state had a policy
of segregating Jews, whereas the Russian policy was to Russify minorities.
By taking on a name in the Russian style, learning the language and
joining the Orthodox Church, people effectively became Russian. If
you were Jewish you might balk at the last step, but the rest of it
could still make perfect sense. Having Alexander as a given name is c
onsistent with this notion because it's very Russian-sounding, no Jewish
associations. There's a good chance that a Jew with this name also had
another Jewish name.
