I found obituaries for both Wells and Avis online in a newspaper archive.
The Racine [WI] Daily Journal, October 11, 1910, p. 2:
"Wells Monroe Cook..born in Cuyahoga County, Ohio, Aug. 30, 1838.Died at Constance, Minnesota, Oct. 4th, 1910, aged 72 years.
As a young man, he left the place of his birth some time in the sixties and came to Wisconsin to the home of his sister, Mrs. James Bell.A carpenter by occupation, he worked with George Brenner in Union Grove and vicinity for a number of years.In October 1871 he was married to Miss Avis Foxwell, of Yorkville, and settled in Racine, where he was engaged for several years as a contractor and builder.In 1885, after a short sojourn in Milwaukee, he moved to Kansas City, MO, where he plied his trade for some years.In 1890 he again moved, this time locating in Des Moines, Ia. where he still worked as a builder, when a stroke of paralysis incapacitated him for further work along that line, but he continued to live there until March 1st, 1909, when he went to live with his brother-in-law, John Foxwell of Constance, Minnesota, at which place he suddenly and quietly passed away on the 4th day of October, 1910, his wife surviving him, and complying with his request, his remains were brought here and laid to rest by the side of his children in Yorkvile Cemetery, Oct. 7th, 1910."
Racine Journal News, January 15, 1915.
"In Memoriam of Avis Foxwell Cook.Born in the town of Caledonia, Aug. 21st, 1846.Second daughter of John and Lucy P. Foxwell.Embraced religion, became a member of the Bible Christian denomination here in her girlhood days more than 40 years ago.Was married to W. M. Cook, Oct. 9th, 1871.She was a gifted musician and the first organist in Yorkville church and Sunday school.Prior to her death she was a trusted employe and nurse in the Northwestern hospital of Minneapolis, Minn. for a few years and on New Year's day of the present year she went to Anoka, about 20 miles distant, to visit her brother and was stricken with pneumonia, the sickness that so speedily ended her life.Four boys who died in their infancy and her husband, who preceded her a little more than three years ago, constituted the family of which she is the last.She entered into that rest, which remains for the People of God and a hope in the resurrection through Jesus Christ, our Lord." [note: does not mention where she was buried.]
I was not able to find a listing of Wells Cook and the four boys in the online listing of Yorkville cemetery.
Avis's whereabouts in several of the censuses is puzzling.She was not married yet, but is not listed with her parents on the 1870 census.Wells and Avis are on the 1880 in Racine, WI.Of course, no 1890 census.On the 1900 census, they are together in Des Moines, IA.However, on the 1910, I cannot find Avis anywhere, but Wells is living as a boarder in the household of John and Mary J. Foxwell in Anoka, Minn.
An extraction of the 1895 Iowa State Census of Des Moines, from AncestryPlus at the library, lists only Wells M. Cook, 57, b Ohio.
Was he the son of Caleb and Eliza Cook of Olmstead, Cuyahoga County?If so, it appears that he had a sister Mary [the one who married James Bell?] and a brother Andrew [based on an entry on the 1850 census of Olmstead, Cuyahoga, OH.I'd appreciate any other info on this family.
I'm pretty well set for Foxwell info, but would be curious about what you might have??
Thanks very much.
