Origins of Polish surnames that end in "o". Are they from ukrainian origins

Many Polish surnames including my own end in o, examples are Bojko, Bajko, Bojdo. Not many names I come across end with o, but I know of ukrainian ones that do. Could names like these originate from what was once eastern poland, around lwow and ivano-frankivsk?

Yes. Bojko is in fact a popular Ukrainian surname.

Not only Ukrainian but Ruthenian in general including Belorusian. Naturally these were most widepread in the eastenr reaches of the old Polish-Lithuanian Commonwealth -- now indepdnent Belarus and Ukraine. Poland's national hero Tadeusz Kościuszko is a prime ecxample. The surname evovled from a pet form of the first name Konstanty -- Kostek, in the east Kostko.

But hundreds of thousands of Poles in today's Poland have names ending in -ko who do not regard themselves as Ruthenian after centuries of polonisation.

Dzienkuje Polonius.
There was always a rumor in my family that we were poles from wołyń that moved to the western territories.

Most of the Poles left stranded behnd Stalin's redrawn border after he annexed the eastern half of Poland in collusion with Herr Hitler were repatriated after the war to the so-called reclaimed territorries in the north and west.

What surname in particular you have in mind?

Bojdo is my name.

Poznań University onomastician Dr Ewa Szczodruch believes Bojdo comws from the Old Polish verb bojeć się (to fear) or the word bój (combat, struggle). It could also have had toponmyic roots - possibly traceable to such places as Bojany, Bojanów or Bojewo. in Germany there is a localtiy called Boyda. The -o ending seems a clear indicator or "Ruthenianness".

I have recently found that my paternal grandmother in Poland has two surnames: one which is Lycba and the other Lyczko. Why is this the case? The area of Poland in which she lived was formerly Germany until after World War II (my father was German with the surname Lyzba). My uncle who still lives in Poland has Lycba as his surname. All very bewildering

The original (primeval) Slavic (Polish) name was Łyczba. It is a Silesian-Little Poland name (Katowice and Sosnowiec have the greatest occurence of this name in Poland).

My surname is Pajdo and is surely not purely "Polish" in origin.

In the early 1960s, there was a family living in Silsden, Yorkshire with the surname of Bojdo.
