Czajka name? And Poland questions. [27]
Any idea of this surname being from Czajka?
Chikosky seems like a American rendition of the Russian surname Tchaikovsky or Polish surname Czajkowski which are essentially the same surname (the fromer i.e Russian surname is more probable because Chikosky is a phonetic rendition (not based on graphic form since the graphic form was probably in the cyrillic script) - the surname means: someone from (or connected to) a place called Czajków or Czajkowo, which in turn most probably comes from the word "czajka" which is a name of a bird that was previously very common in Eastern Europe (according to wikipedia it is called peewit in English (Lat. Vanellus vanellus))
surnames ending in -ski (sometimes -cki or -dzki) were previously associated to nobility in Poland but it was never a strict rule (well also nobility adopted surnames much earlier than peasants, in Poland)
I may well be wrong but your great grandfather might have been born in Taganrog (it is the only city in Russia that is called similarly to your version) - Taganrog is a city in southern Russia (not a very big one, mind you) not far from Rostov-on-Don (however it is entirely possible that Tagalog is some small place I have never heard about)
