Where is Pickens,Co Arkansas?

I'm hoping someone can help me. I can't find Pickens, Co Arkansas. I found John T. Huff married Nannie Hardwick on 4/27/76. in Pickens,Co Arkansas. Nannie died after the birth of the first child. John Huff remarried second wife in pickens,Co Arkansas. I'm trying to find second wife's name and marriege record. Thank you, Lynn
