Well, good news and not so good. I found Jasper's WWI draft card - born 8 Nov 1891 in Oklahoma, lived in Plainview bef 1920, was a barber. Found Minnie in 1930, but no Jasper. She is listed with two daughters - Bonnie J born abt 1922. They are listed as housekeeper and daughters. So, it looks like Jasper either left or died bef 1930.
