Here is a transcription of Jeremiah's obit as shown in the newspaper clipping image. Burial on Wednesday allows you to determine burial date.
"Jeremiah Younkin, a former resident of Clay county, an early settler here, died Monday, February 25, at his home on Timber creek, with a complication of diseases incident to old age. The deceased was seventy-nine years old, and the funeral occurred on Wednesday at eleven o'clock A. M., and the remains were laid to rest in the Milford cemetery. The deceased leaves a wife, two sons and three daughters, and one sister, Mrs. D. H. Myers of this city. The deepest sympathy of a host of friends of the afflicted family is extended to them in their hour of bereavement." -- (Clay Center Times, March 7, 1907.)

"In April, 1856, Moses, William and Jerome Younkens and John P. King [Moses' mother was Mary King], settled near the mouth of Timber Creek. They were the first white men to permanently locate within the present limits of Clay County, and it is pleasing to add that all except Moses have continued to make this locality their home. Shortly after them came J. B. Quimby and William E. Payne, and took up claims on the west side of the river, south of Wakefield. Lorenzo Gates and John Gill settled near Deep Creek in the fall of 1857. At the same time William Mall took the claim where his brother Jacob now lives, but remained only two years, returning to the East. In 1857 Peter Dobbins took a claim at the mouth of Pete's Creek, which event gave a name to the creek that before had only a "local habitation." He soon went to Texas, but returning found that he had forfeited his right, and that the claim was in possession of William Silvers, who still occupies the farm. During the two succeeding years, a large number of settlers came into this neighborhood.
"The drouth (sic) of 1860 quite completely stopped emigration until after the war, when after five or six bountiful harvests the settlers came in plentifully, and the county commenced a new era of progress, which with the exception of 1875 has been rapid and substantial.
"Most of the settlers after the war were soldiers who came to take advantage of their soldier's claims.
"As stated, the first settlers of Clay were Moses, William and Jeremiah Younkens and John P. King, who came together from Pennsylvania, and settled in the county in April, 1856. Mrs. Moses Younkens was the first white woman and Mrs. J. B. Quimby the next.
