By 1940 Walter was a widower, living in Farmington, Warren, Penn.
Here is a WWII draft card for Walter:

Nearest Relative: Mrs. Florence Mahan, Russell, Pa.
Florence might be his daughter, and therefore of course, sister to Harold.
This might be Florence in 1940:

This might be a death record for her:
