You must have seen the marriage certificate for Jack Robert Sadler and Charlene Gowens, m. 21 Dec 1946, which names his father Jack Robert Sadler, native of Kentucky.Also, the 1940 census shows Lillian's age as 41, with dau Betty Meek b. 1921-'22 and son Jack R. Sadler b. 1926.From that, Lillian must have married Jack Robert Sadler ca 1923-'25, most likely in California.Considering "Jack" is a nickname for John, the task becomes more difficult finding your Jack.There are many unconnected Sadler lines in Texas and the one I have followed has no Jack Robert Sadler, b. ca 1895-1900--considering he would have been about the age of Lillian--that I have found. GOOD LUCK--if you are still looking!!
