First, I tried plugging in all the information that I had about him into Ancestry and FamilySearch, but I found nothing useful. I got a lot of family trees that had been put up by descendants of his wife's family [Aganetha Heidebrecht #319927 (1882-1947)], but they had no information about his parents. I decided to try his marriage license, death certificate, and obituary since those are common sources for parents' names.
Since he was Kleine Gemeinde, I figured that Christlicher Familienfrend, the denominational paper of the KG, would be the most likely place for an obituary. The nearby Mennonite Library and Archive at Bethel College in North Newton, Kans., has the Christlicher Familienfreund, and it was easy to find his obituary in the July 1939 issue, the month after he died.

From Grandma I knew that he had married on 7 May 1905, in Jansen, Nebr. Recently I was in Fairbury, Nebr., the county seat of Jefferson County where Jansen is located. The FamilySearch wiki for Jefferson County, Nebr., reports that the county kept marriage records from 1864, so I should be in luck. And the county clerk indeed had his marriage record to Aganetha Heidebrecht.

I'm sure that his father's real name was not "Frank Glen" because "John Glen" was the Americanized version of his Polish name, Jan Glein. So his father's surname was surely "Glein." And Franciszek is the Polish version of the name Francis or Frank, so I am sure his father's real name was Franciszek Glein.
I think it says something that he didn't know his mother's name. Most likely his mother died when he was young.
BTW, I haven't checked the death certificate yet, but it would be interesting to see if the informant knew his mother's name, although I doubt it.
