Seems unlikely he was involved. I can’t find the book to check for myself, but this is from the wiki page for Strange As It Seems:
The cartoon strip was written and drawn by John Hix from 1928 until his health began to deteriorate in the early 1940s and Dick Kirby began drawing the strip, although Hix continued to oversee and approve all content.
John Hix died of myocarditis on June 6, 1944 which (strange as it seems) was also D-Day. His brother, Ernest Hix, took over producing the feature. The cartoons were drawn by Dick Kirby from 1944 to 1946, then by Doug Heyes from 1946 to 1948. After Ernest Hix’s death in the crash of a private plane on September 18, 1948 in Los Angeles, the writing of the strip was taken over by his wife Elsie Huber Hix. Ms. Hix had two young children at the time, Ernest Harmon Hix Jr. and Dixie Ann Hix. Dick Kirby returned to draw the strip from 1948 until 1949, then George Jahns took over and continued as the feature’s artist until 1970 when the strip was discontinued. Ms. Hix continued to write the stories for the comics until 1963, when she turned the work over to her son, Ernest Hix, Jr. He wrote and produced the strip with his wife Phyllis until 1970 when the feature went out of syndication.
But if I see anything about him later, I’ll let you know!
