There's almost no personal info on this death cert, even though the informant is one of Orville's younger sisters, Carrie Steiner Traxler. For some reason, "unknown" is the father and "unknown" is mother's maiden name.
And the info that appears on the death cert makes no sense. Orville was apparently married, but the name of his wife is "unknown." Poor Orville died of uremic poisoning, on top of chronic myocarditis. He was 80 and living in Marion, Ohio, not far from Carrie and other sisters, who lived in Upper Sandusky, Ohio.
I'm remembering him on Sympathy Saturday. **
** Update: I've just discovered more about Orville by tracking him back through the Census. In 1930, he was an "inmate" at an almshouse. My assumption (not proven) is that he was in the almshouse when he died, and the officials listed his next of kin as the "informant" without actually consulting her about details such as Orville's parents' names. He really has my sympathy now.
2022 update: I've been in touch with Orville's descendants, who say he had some kind of chronic illness that required long-term care.
