John K. Rainwater Has Been Prominent Citizen of This County Since 1865 --

John K. Rainwater, one of Columbia's earliest settlers, passed away Sunday morning at 9 o'clock at the home of his daughter, Mrs. William Robinson. He was 86 years of age and almost his entire last year was spent in illness.

John Rainwater was born in Tennessee January 3rd 1834, and in early life moved to Arkansas. From there he came to this country in 1865, and ran a sawmill in partnership with the Robinett for whom the mountain is named. At one time Mr. Rainwater had a large farm in Asotin county, and was also a wheat farmer there. He was identified with the Chronicle for a while with his son-in-law, O. C. White. He was very successful in all his business ventures and was able to retire some years ago.

After Mr. Rainwater had lived in this country for a number of years, and had amassed considerable money, he made a trip to his old home in Arkansas, and was so enthusiastic in his praise of Washington that he induced a number of friends to come out here, among whom were the Hanger, Honeycutt and Gillis families.

The funeral was held from the Robinson home Monday afternoon at 5:30 o'clock with Rev. W. C. Gilmore of the Congregational Church officiating, and the service at the grave was conducted by the Masonic Order, of which Mr. Rainwater had been a member for over 50 years.

The deceased is survived by six children, who are: Arthur Rainwater of Casper, Wyoming; Mrs. Lilah Muncy of Spokane; Mrs. O. C. White of Olympia, WA; Mrs. Wm. Robinson of Dayton; Mrs. Frank DeSerlay of Seattle; and Mrs. Frank Green of Pasadena, CA.

J. K. RAINWATER DIES
He was half-brother of James D. and William F. Rainwater. The death of J. K. Rainwater at Dayton, Wash., is announced in a paper received by James D. Rainwater. John K. Rainwater was a half-brother of James D. and William F. Rainwater of this city. It has been many years since he visited here. He was present at the laying of the cornerstone of the city fire department headquarters, December 27, 1883.

Mr. Rainwater, who was 86 years old, was born in Severe [sic] county, Tennessee, and settled at Albany, Ore., in 1861. He removed to Dayton, Wash., in 1879. At that time Dayton was a frontier outpost. Land that he settled on is now included within the city limits and is known as Rainwater's addition.

Mr. Rainwater is survived by six children. He was a member of the Masonic lodge for over 50 years, being one of the oldest members in that state. Because the funeral took place before the notice of death was received in Carthage, either of his half-brothers will go to Washington.
