Does anyone have a death date for this person? I can't seem to dig it up. I'd be grateful for your help.

Edwin Langxton Salisbury
b 4 Feb 1883
+
Martha Pittman (Salisbury)
b abt 1882

They lived in Franklin, Greene, Iowa.

Willard Salisbury was their son, b abt 1908. But it is his
father, Edwin, above, whose death date and place I can't locate.
I believe the families were from New York, Pennsylvania and some in Illinois before moving to Iowa, which is where they seemed to stay for quite some time.
They lived very near the Pittman family, which was Martha's maiden name.

ANY help would be wonderful! And I'm always glad to return a favor when I can.

Thanks much,
