The Windsor Review, Windsor, Missouri, 08 Mar 1934, p. 1 (Obituary):
Walter Chastain was born near Cloverdale, Missouri, February 23, 1856, and lived in that neighborhood until eight years ago. Upon the death of his wife, Mary Belle Gallaher, he moved to Seattle, Washington, to be near his seven children.

In the fall of 1930, he returned to Missouri for an eighteen months' visit with his sisters, Mrs. Harry Reid and Miss Roberta Chastain. Upon leaving Missouri in 1931, he traveled through Oklahoma, Texas, and Arizona, visiting friends and relatives, terminating his trip in Los Angeles, California, where he lived with his son, Howard, for eighteen months. During that time he attended the Olympic Games and experienced one of the worst earthquakes in the history of the state.

In June 1933, he went by boat to Seattle with his son, Howard, later going to Gresham, Oregon, where he spent the summer with his son, Huse.

In the fall of 1933, he moved to Portland, Oregon, and spent the remainder of his life at the home of his son, Howard.

He was ill for fourteen weeks and passed away on February 24th, one day after his 78th birthday. All his children were present.

He is survived by seven children: Robin, Ross, Huse, Howard, Charlie, Ruth and Maude, eight grandchildren and three brothers, George, Jake, and Edmund; three sisters, Roberta Chastain, Mrs. H. S. Reid and Mrs. Ora Kelley.

Mr. Chastain lived a full and happy life, greatly respected by all who knew him. He had a great philosophy of life which is expressed in his diary, which was written upon the occasion of his leaving Missouri on his last trip:

"It is hard to give up old home ties, old associates and surroundings of almost a lifetime, but my observation has convinced me that human nature is the same the world over. Dependable people are the same the world over. To be a friend is to find one."
