My grandfather (James Max Peck) was briefly married to (the former) Minerva Henke from around early 1938 until he died at the end on 1939. I know it is the same Minerva Henke in Tulsa as I have his address (on Quebec Ave in Tulsa) at the time of his death and the newly released 1940 census lists his wife Minerva as having been born in Missouri. The 1940 census also lists a Mildred L Henke (age 17) as living there in April 1940.
