Hi Bobrka,
I think you still misinterpret the notions of citizenship and nationality.
You wrote: “And the law say that the person who born in 1900 in these territory, if was a man, the nationality or citizenship was directly taking from his father. They said his citizenship was continue by blood not for the territory where he born. And if the person was a woman, she take the nationality of his husband.”
Are you writing about nationality or citizenship there?
According to dictionary: citizenship is the legal status of being a citizen of a country.
You may find also many other definitions at:

If your grandmother or grandfather were born in Austro Hungary in 1990 to the citizens of Austro Hungary they were Austro Hungarian citizens. If your father was born in 1937 he could not be considered as Austro Hungarian citizen because Austro Hungary did not exist at that time. Also it is unlikely that he was considered citizen of Poland, which was legal successor of Austro Hungary with respect to Galicia, but it is possible because if your grandfather immigrated in 1927, he already became citizen of Poland (starting from 1919-1920).
Citizenship is something that can be changed when you immigrate to other country and fulfill all necessary requirements that are different in each country. There are also countries that allow double citizenship, for example, Panama. For example, former Prime Minister of Ukraine, Lazarenko, who is citizen of Ukraine, had also Panama citizenship, and correspondingly Panama passport, that allowed him to travel throughout the world without the need for any visa.
You may consider citizenship as a marriage, which is binding legal commitment, but which allow legal cessation of this commitment, end entering another. By analogy, some countries allow few wives.
Nationality or ethnicity is different, and it relates to the parents. It is something that cannot be changed, and does not depend on where you where born and when. It is more related to religion, customs, language and self-identification of parents. When both parents belong to one nationality then nationality of child is automatically determined. If there is mixed marriage, then nationality is determined according to customs and rules of thumbs of the particular country and time period. In the case of Galicia, and mixed Polish-Ukrainian marriages, you should look at the religion, church where child was christened. If it was Roman Catholic then nationality would be Polish in majority of cases. If Greek Catholic than Ruthenian (Ukrainian). But I think that it is very artificial, and if there was mixed marriage, the child nationality was also mixed.
I know that different nationalities have very different approaches to this question, but I just want to show you the difference between citizenship and nationality. Nationality is very deep question and you would need to consult some specific literature for each particular case.
