Evelyn A. Streck born about April 1919 had three sisters, two who married Kizior brothers. I believe Evelyn A. Streck never married, so she couldn't be the same Evelyn that you are looking for. The two Streck sisters who I know married Kizior brothers are Marian, b 25 September 1925, who married Edward Kizior, and Pearl, b. 11 March 1924, who married Walter Kizior. The fourth sister married into the Maliska family.
There is another Evelyn K. Kizior listed in the SSD. Her age is in the right ballpark:
