BLM records show two land grants to John J Piper in Spokane County, 1888 and 1889

From relative:
I am also interested in finding information on a great-uncle, his name was Dr. John J. Piper and he lived in the state of Washington. I do know he was still living in 1887 when his mother died. I have also found the following information. "On March 18, 1881, Mr. Marcus D. Wright was united in marriage to Miss Bertie Piper, a daughter of Dr. John J. Piper, of Peone Prairie, Washington, who was for twelve years one of the county commissioners of Spokane county, Washington. Mrs. Wright passed away in 1901, being survived by her husband and seven children, two sons and five daughters". I have no other information on him.40

John J. Piper is listed in the 1900 Washington State Census, occupation farmer. He’s listed as a widow and is living with one daughter Carry Aneta and his granddaughter, Bertie D. Wright. Her parents are still alive at this time, so I have no explanation for her being with her grandfather. Her mother dies the next year, possibly in childbirth (there’s a Wright child in the family plot who appears to have been born and died the same month) Marcus Wright (father) will pass away in 1916.(Doug Jones)12

Dr. J. J. Piper, a pioneer of 1879, is a native of Tippecanoe county, Indiana, born April 6, 1831. While he was yet a boy, his family moved to Clark county, Ohio, and he grew to manhood there, but in 1852 came to California and engaged in mining enterprises. In 1856 he began the study of medicine with Dr. Elias Jones, of Wolf Lake, Indiana and attended lectures at the Indiana Medical School at LaPorte. He practiced as a physician for twenty-nine years afterward, then came to Spokane county and homesteaded one hundred and sixty acres of land on Peone Prairie. Subsequently he purchased a half section more, so that he is now the owner of a fine farm of four hundred and eighty acres. In addition to his farming, he still practiced his profession for a time among the residents of the prairie, but is now retired from the work. Dr. Piper is looked upon, by those best acquainted with his abilities, as an excellent physician, and his many amiable qualities as a man render him a universal favorite. Though quite an old man now, he still takes an active interest in all matters of local concern and occupies a place among the leading and representative men of his community. He was a member of the second board of county commissioners in this county, and has served as a commissioner twice since. The Doctor is one of the oldest, probably the oldest, member of the I. O. O. F. in the state of Washington, having joined the order in March, 1852. He was married in California, in 1859 to Elida Kirkpatrick, and they have two daughters: Albertina Jane and Carry Aneta. Mrs. Piper died in California in 186861

Another source has John J and Elida R marriage as 1862..62
