By great coincidence, my late father, a U.S. Army infantryman, was aboard DAY STAR on a voyage from San Francisco to Guadalcanal, possibly on the same voyage that you report that Newman Frederick McKinney was also aboard.
According to information I was able to find, there was a Newman F. McKinney who resided in Benzie County, Michigan. Specifically he may have lived in the tiny town of Almira, Michigan, in that county. (By another coincidence, my brother and sister-in-law recently purchased property in Almira for a vacation home. My family is from Michigan.) He also had a rural address in Empire, Michigan, which is in the next county to the north, Leelanau County, and is about 16 miles from Almira.
Here is an obituary I found for Newman F. McKinney, published October 20, 1977, in the Traverse City Record-Eagle:
"Newman F. McKinney, 73, of Route 1, Empire [Michigan], died Wednesday [October 19, 1977] at Leelanau Memorial Hospital in Northport [Michigan] after an extended illness. He is survived by one daughter, Mrs. James (Patricia) Leymon of Albuquerque, New Mexico; a cousin, Mrs. Gene (Arlene) Luppino of Pontiac [Michigan]; and two grandchildren. He was preceded in death by his wife, Jennie, in 1976. Mr. McKinney was born January 3, 1904, in Pontiac [Michigan]. He made his home in the Traverse City [Michigan] area for most of his life. He was a commander in the U.S. Navy and a veteran of World War II. He worked for the Michigan State Highway Department as a civil engineer and retired in 1966. The funeral is scheduled for 2 p.m. Saturday [October 22, 1977] at the Hibbard Funeral Chapel. Burial will be in Woodlawn Cemetery, Detroit."
I will send a private e-mail to you with additional information.
