thank you for your opinion :)

I found out
Weinar/Vejnar surname is German origin. Weinar: From German personal name Woiner, and this from Wagner


Haman is of German origin same as Hamann.

Nadvornik is Czech

Burda ?

Jansa? I was told Slovene or German for John ?

Ledvina also could be Czech?

Weinar looks like germanized Polish surname Wojnar.
Burda may be Polish because it means "riot" ;)
And Jansa may be related to heraldy of some Slavic country,because its similiar to Jaksa ,Sarmatian name used in Polish noble heraldy.
