Topolovec family postcard

A photo of a postcard sent from Yugoslavia to the Topolovec's in Utah. I don't know if "Fathers folks fam" means August's parents and siblings or if they are extended family. The two adults in the middle resemble the older couple in another postcard. So I'm assuming they are Marko and Franca (Vinceljak) Topolovec and August's siblings. And I'm guessing August's brother Stefan Topolovec is who sent the postcard.

If anyone can/wants to translate this for me that would be amazing :)

translation and names of those pictured.
