Information about your ancestors may be contained in the state archives of Belarus or Poland (with a low probability). At the same time, without knowing Russian or Polish, respectively, it will be very difficult for you to interact with these institutions. In Belarus, you may have additional problems when contacting the state archives, since you are not a citizen of Belarus. You are not in any danger in this case, but you may be refused cooperation or will need a lot of additional documents, for example, that you are a scientist historian (all documents with notarized translation into Russian). But even if you manage to establish interaction with the Belarusian state archives, you will wait a very long time for an answer, and the probability that the answer will be: "Nothing found" is very high. I cannot say for sure about the situation in Poland, I only know that the level of digitalization of archives there is a little higher, and perhaps some things can be done even online. There is a vanishingly small probability that some information about your ancestors may be in the local authorities of the Sharkaŭshchyna district and Vitebsk region. But I am almost certain that you will not be able to establish cooperation with them without knowledge of the Russian language and Belarusian citizenship. What you can definitely do is come to Belarus. At the border with Belarus, you will need a considerable package of documents to enter the country (I do not know exactly what set of documents and cannot advise, you need to find out on the website of the consulate of your country in Belarus), but you will definitely be able to enter, visit the village Luzhki, and at the same time Minsk and something else, and safely leave Belarus. At the same time, nothing threatens you. You will also be pleasantly surprised by the hospitality of Belarusians and the level of service in Minsk. Taxis, hotels, restaurants, souvenir shops, all kinds of entertainment will be at your service. In the capital, you will be served in English in most tourist sites, and everything will be fine, familiar and very pleasant. But the level of tourist service in the Sharkaŭshchyna district and the village Luzhki is very harsh, almost no one will know English there, it may be very difficult to find accommodation and transport. The Sharkaŭshchyna district is one of the most sparsely populated and poorest in Belarus. When going to the village, you can only be sure that you will be able to buy food there in a grocery store, the rest must be carefully planned in advance. You should seriously prepare for the trip from Minsk to the village Luzhki. In Minsk, you can rent a car, perhaps this will help you. Thus, if you just want to see where your ancestors lived, then you can do it. It will be an interesting adventure full of new emotions and unforgettable impressions. If you want to find information about your ancestors in old documents, then most likely you will waste your time. And you will certainly not find, learn or hear any such information when visiting the village Luzhki directly. There you can only look at the land of your ancestors, take a walk, enjoy nature, admire the Catholic church, breathe fresh air, feel the local flavor. But you won’t learn any new specific information about your ancestors there...
