The first photo is identified as Uncle Quin Bryan and wife. The photographer's stamp is Nelson-Long (possibly Lang) of Moxie, Kansas. The address label on the reverse shows it once belonged to a Doris Lewis.
Only two of the ladies in this nice group photo are identified. The second from the left is Minnie Bryan Moore and the fourth from the left is Zora (or maybe Tjora) Bryan Hutchinson. The photographer stamp is Smith of Chicago. This photo does not have an address label affixed, but I suspect it is related to the first photo because of the handwriting on the back, which has some of the same peculiarities in the "Q" of Quin and the "Z" of Zora.
