Genealogy / Lesowiaks - who are they? [6]

I found a short article about lesowiaks in a book about Poland, but then I haven't find a word about them on the internet. The book says that lesowiaks live in Kotlina Sandomierska, near Rzeszów. They are a small, proud and free ethnical group, who keep their old traditions. Kolbuszowa has a museum which can give a taste of their traditions.

But that's all, no more informations at all. If somebody could write me some more words about this interesting group, I would be much obliged.

Language / pierwszego/pierwszy [11]

Hello, please help me! I don't really understand the declension of the adjective in this sentence:
Jem dzisiaj dopiero pierwszego hamburger.

Can somebody explain me why is this pierwszego, not pierwszy? I know hamburger is a masculine noun, and it's in ACC with its adjective, but I thought that adjectives get -ego ending only if the noun is a masc. living thing.

Thanks a lot in advance...!

Language / Kowalski+Kowalska=Kowalscy [12]

Hello!
Please someone help!
Pan Nowak+Pani Nowak= Państwo Nowakowie, am I right?
But...
Pan Malicki and Pani Malicka is Państwo..... ????
And
Pan Janik and Pani Janik... Państwo Janikowie?

Language / The usage of "dwoje" [11]

Maybe it's a stupid question, but I really don't know when it is used... I know the forms of dwa, but not this one... only dwa, dwie, dwóch, dwaj and the like.

So... please someone explain me: what is this dwoje???
Thanks a lot in advance :-)

Language / Jakoś tam będzie [4]

Cześć:-) Please help!

I know what it means literally, BUT I guess it has a figurative sense, hasn't it? Just because I heard it from Poles, and I don't really understand this expression...

Language / Jestem za [11]

Can I use this expression in everyday situations, when I want to say that I line up with my partner?
Because I found it in a dictionary, and it said: "Jestem za" - "I agree". Do you use it often in Poland or should I use an other expression?

Language / Tego/Jego [15]

Witaaj!
I had a ćwiczenia in my Polish exercise book: to convert the object of the sentence into personal pronoun accusativus. And I and my teacher were disagree and I don't understand why I was wrong.

The sentence:
Andrzej myje samochód.
And we had to replace the word "samochód".
I used "tego", but my teacher said the correct replacement is "jego".
Andrzej jego myje.
But why??? Jego is the Acc. of On, but 'On' is a male person, a living thing, isn't it? So a "samochód" can only be "To", because it is not a person, it is only an... it.

To=It
On=He
Am I incorrect??
