Looking for two cities likely in Poland 1882/1883

I have reason to believe that family members of mine arrived in Poland between 1880 and 1882. In a church book fra Latvia 1883 a city named Lantzky/Luntzky or similar is mentioned. In addition I am looking for a city probably named Lubsky/lupsky. Can anyone point me in a direction?

There is a town called Lubsko but it belonged to Germans 1700-1945 so your Jewish ancestors probably didn`t settle there.

Besides, a location in Poland can`t bear the sole name of Lubski - it sounds as an adjective.

Thank you pawian. I shall keep looking. My family were Danish Lutherans.

Oh, Danes? I thought they were Jewish coz you mentioned Latvia. There was a huge immigration of Jews into partitioned Poland at the end od 19th century. After they were expulsed by Russian tsars, mainly from the Baltics, they settled in Polish cities.

There's a town/parish called Landzani in former Latgalia, the part of Latvia which belonged to the Polish Commonwealth until 1795. Landzani is a Latvian name, but the name used until 1795 may have sounded a bit different.

Thank you so much Ziemowit. I think it's getting warmer. I see that the town is actually still called Landzāni and is located close to the railway (according to a map from 1881) which makes a lot of sense. Thanks again, I'll investigate further.
