I was at a conference in Lincoln and went to the Nebraska State Historical Society next door over lunch and photoed the actual obit. There weren't any other Brezinas in Margie Sobotka'a index, but there was a Jaros. This might be relevant because he was located in Pennsylvania, like your Brezina line. Attached.
With the clue from the obit that Anton arrived here in 1900, I did find one record in Ancestry, arrived 23 Nov 1900 in New York on the Kaiser Wilhelm. If this is your Anton, his brother appears to be Johann. Lines 19-20. The record does continue to the next page, but there's no real info there. Also attached. It will be interesting to see how the more skilled readers transcribe the place of origin. I can only decipher about 3 letters in the name.
