Protas B. Blume

Protas B. Blume

Co. B, 14th IND. Infantry
Pages 730-732, History of Allen and Woodson Counties, Kansas: embellished with portraits of well known people of these counties, with biographies of our representative citizens, cuts of public buildings and a map of each county / Edited and Compiled by L. Wallace Duncan and Chas. F. Scott. Iola Registers, Printers and Binders, Iola, Kan.: 1901; 894 p., [36] leaves of plates: ill., ports.; includes index.

Under circumstances which would have utterly discouraged and disheartened a man of less resolute spirit and earnest purpose Protas Blume has worked his way upward to success. At times fate has seemed to be adverse and obstacles and difficulties have barred his path, but perseverance and energy have conquered all, and to-day Mr. Blume is living in honorable retirement in a pleasant residence in Yates Center, his toil in former years having brought to him a competence which now supplies him with all the necessities and many of the luxuries of life. If more young men followed his example, the word "failure" would appear less frequently in connection with biographical history.
Mr. Blume was born in Strasburg, Germany, May 6, 1832, and there spent the first ten years of his life, after which he came to America with his father, Joseph Blue,[sic] in 1842. They landed in New York City and then went to Cincinnati, O., where the father died of cholera at the age of fifty-eight years. His wife had died in Germany prior to his emigration to the new world. Our subject, then a young boy, engaged as an apprentice to learn the tailor's trade and was employed in Cincinnati for five years, after which he removed to Moorfield, Indiana, where he secured a situation as a farm hand, working by the month.
As a companion and helpmate on the journey of life he chose Miss Christiana McKinzie, who was born in Switzerland County, Indiana, in 1823, and was of Scotch lineage. Their marriage was celebrated on the 19th of January, 1858, and Mr. Blume continued farming in the Hoosier slate until 1862, when feeling that his country needed his services he enlisted as a member of Company B, Fortieth Indiana Infantry and participated in the battles of Nashville and Franklin. In the latter he was severely wounded in the back of the head and for a long time lay ill in the hospital, after which he was discharged on accouet[sic] of his injury, after serving for nineteen months.
Mr. Blume then returned to Indiana and as soon as he was able he and his wife removed to Madison County, that state, where he used the money which he had saved in the army to make partial payment upon a farm. To make the purchase he incurred an indebtedness of five hundred and sixty-three dollars. He labored hard and at length acquired the money with which to make full payment. On the 2d of December, 1867, therefore, he started for the recorder's office with the money, but the man to whom he owed it failed to meet him. He then started to return and while crossing a bridge he was attacked by highwaymen, knocked senseless and the money taken from him, the robbers making their escape. This was such a discouragement that Mr. Blume resolved to lose what he had already paid on the farm and go to Kansas where he could obtain land from the government. Accordingly, in the spring of 1868, he arrived in Humboldt, Kas., with only a dollar and sixty-five cents in his pocket. The next day he began work for William Lassman at hauling sand. After three months he filed a claim to one hundred and sixty acres of land in Eminence township, Woodson County.
Since that time Mr. Blume has devoted his energies to agricultural pursuits, and has made one of the finest farms in the county. He has since taken one hundred and sixty acres of land each for two of his sons, and his home farm comprises two hundred and forty acres—a valuable tract on which is a fine residence and three large barns together with many other improvements. The cattle barn will accommodate sixty-five head of cattle, and he has two barns for the horses, together with cow pens and other buildings, somewhat resembling a little village. On the place is a fine grove of maples, containing ten hundred and twenty-eight trees in rows four feet apart in one direction, six feet in the other. At the well there are also nineteen trees, which were planted by his wife, who pulled up the switches and carried them home, planting them in their present location. They are now two feet thick and one hundred feet in height and stand as monuments to Mrs. Blume. As the years have passed Mr. Blume has met with a high degree of success in his farming and stock raising operations, and with a handsome competence sufficient to supply his wants throughout the evening of life he has retired to Yates Center where he is happily and quietly living with the wife who through more than forty years has been his faithful and devoted companion of life's journey. They took up their abode in the city November 15, 18

Joseph King

Joseph King

Co. A, 12th IND. Infantry
From History of Montgomery County, Kansas, By Its Own People, Published by L. Wallace Duncan, Iola, Kansas, 1903, Pg 645-646:

King, Joseph F. Bio

The “old soldier!” How shall we repay him, how measure the value of his services to his country? Shall it be in paltry dollars and cents? Far be it from us, the beneficiaries of their loyalty, to think that the mere pittance received as a pension, discharges the obligation owed to them! Let us, in the few brief years they are to be here, pour forth upon them, in addition, the benedictions of a grateful posterity. Stand with uncovered heads, as each year their lessening ranks file by, resolved that the glorious country which they saved with their blood, shall continue its benign mission of uplifting humanity to a higher plane of excellence. The biographer is always proud to record the few brief facts that tell of duty done in the dark days of the Rebellion, and, in Joseph King, of Caney township, is a subject which furnishes the necessary material.
Mr. King landed on Kansas soil in 1857, and was, thus, in the thick of the fervid battle for supremacy, then going on between the forces of the Free-State patriots and the Border Ruffians. When the war cloud actually burst, he was one of the first to enlist, first, in the Home Guards, and then, in a company commanded by Capt. J. B. Forman, which became part of the Tenth Kansas Infantry. After a year’s service in this organization, he received honorable discharge, and, immediately, returning to his old home in Indiana, reenlisted in Company A, of the Twelfth Indiana Volunteer Infantry. In this company he served during the remainder of the war, participating in many of the hard-fought battles and long wearisome marches of the Army of the Cumberland, and, later, with grand old “Uncle Billy,” to the sea. A partial list of the battles in which Mr. King had a part, follows: Richmond, Kentucky; Siege of Vicksburg, Jackson, Missionary Ridge, Resaca, Big Shanty, Big and Little Kennesaw, Atlanta, Jonesboro, Macon, Savannah, Columbus, Bentonville, Raleigh, together with numerous other skirmishes, not mentioned in the reports. At Richmond, Kentucky, Mr. King was unfortunate enough to get within the enemy’s line and was captured. He, however, was paroled on the fourth day. Again, at Atlanta, his zeal carried him too close to the enemy. His stay with the “Johnnie Rebs” was even shorter than before, as he was enabled, by he lax discipline of the guards, to make his escape, and to participate in that “glorious march to the sea.” His company had the distinction of being selected to lead the Grand Review at Washington, an honor which it richly deserved, and which its battle scarred members bore with distinguished credit.
A few brief facts concerning the family of Mr. King will not be amiss. He was born in Jennings county, Indiana, on the 17th of September 1842, a son of George W. and Nancy (Boyd) King. The parents were natives of Ohio and, in 1857 removed, with their family, to Anderson county, Kansas. Here, they lived out their days, as farmers, loyal to the free institutions of their adopted state, which the father served during the war, in the home guards, and in several different offices of trust. He died at the age of sixty-eight, the mother surviving him an dying at seventy-four years. They reared a family of twelve children, the four now living being: Joseph F., Elizabeth, William and Robert C. Those deceased are: James, David, Benjamin M., Emma, John, George, Lena and Cynthia.
Upon his return from the war, Mr. King was joined in marriage with Catherine F. Lewellin, the date being June 24, 1865. Mrs. King was a native of Jennings county, Indiana, born the 20th of November, 1844, the daughter of James and Sidney J. (Scroggins) Lewellin, who were from South Carolina, and early pioneers to Green county, Indiana.
The year of his marriage, Mr. King returned to Anderson county, Kansas, where he engaged in farming until 1883, when he bought his present farm of eighty acres in Caney township. It lies two miles south of the village of Havana, and shows the care of a practiced hand, in the many substantial improvements to be found thereon. Mr. King is a man of parts, in his township, having served as treasurer and clerk of the school board a number of times, and in various other positions of trust. In political belief he is a staunch Republican, and delights to promote the interest of that party. To him and his wife have been born a family of ten children, but four of whom are living: Nancy, wife of Fred Wolsch; Minnie, wife of David M. Spring; Joseph D. and Amos. Those deceased are: James, Mary, George, Etta J., and John A.
Mr. and Mrs. King and their son, Amos, comprise the family living at home, and all are regarded with much respect in the community.
