Col. S.B. Rohrbaugh Passed Away At Excelsior.
Body To Arrive Tongight
Funeral Will Occur Thursday From The House
Settlement of the Estate To Involve Question of Mental Soundness.

Col. S.B. Rohrbaugh, of Ottawa, died suddenly yesterday evening at Excelsior Springs, whither he had gone for the benefit of his health. Mrs. E.P. Hubbard and Miss Nelle Hubbard were with him at the time of his death. S.R. Hubbard and wife left this morning for Excelsior Springs, and will accompany the body home tonight at midnight. It is announced that the funeral will be held on Thursday at 2 p.m. from the residence.

From the information conveyed in brief messages announcing Col. Rohrbaugh's death, it seems that Colonel Rohrbaugh was seized about 4 o'clock yesterday with an acute attack of stomach trouble. Physicians were summoned and medicines intended to relieve the attack were given. A short time later, while in the toilet room, Colonel Rohrbaugh was fatalally stricken, and died in a few minutes. Col. Rohrbaugh had been in poor health for the past year.
To Ottawa in 1869
Col. Samuel B. Rohrbaugh reached Ottawa on the evening train on the first day of December 1869, bound west from Springfield, Ill. to make his fortune. The road ended here then. That train brought two buisness men destined to make large places for themselves in a little new village. J.C. Armstrong and Colonel Rohrbaugh met at Lawrence, and each discovered that the other was coming to Ottawa to start buisness where there was a chance to grow up with the country. Born of Pennsylvania Dutch parentage, back in the Pennsylvania mountains, Colonel Rohrbaugh had come out to Illinois fifteen years before his start in Kansas. He began as driver of a wagon in the lumber yard of S.M. Kinsley, at Springfield, and afterward worked up to a better place. When B.C. McQuesten and his associate, Mr. Shepherd, engaged in the banking buisness here, they thought of Mr. Rohrbaugh-whom they had both known at Springfield-and wrote him to come on.
Began with the year 1870
The new arrival attempted no buisness transactions on New Year's Day-the day following his arrival in Ottawa-but on the next day he closed the purchase of the then McGhee lumber yard, which fronted on Third street where Rohrbaugh yard is now located. Then began a long career of uninterrupted buisness sucess. Mr. Rohrbaugh acquired property rapidly. Deliberate and conservative in his dealings, he never ceased to "get ahead" financially, and one after another of Main street properties came into his possession to afford sites for handsome buisness buildings.
It was about thirty years ago that Colonel Rohrbaugh was married at Garnett to Miss Wilhelmina Stevens, sister of Mrs. E.P. hubbard. Mrs. Rohrbaugh lived but a few years leaving a son Ed Rohrbaugh, whose death at the age of twenty-one occured some six years ago. Colonel Rohrbaugh had no near relatives with him as old age came upon him. A sister lives out in western Kansas, and a brother and sister are said to be living in Pennsylvania, but there has never been any intimacy between Colonel Rohrbaugh and these relatives. For oerhaps twenty-years he had quarters in the apartments above the lumber office, until the handsome new residence was built just south of the Rohrbaugh opera house, to be the home jointly of Colonel Rohrbaugh and the fanily of Mrs. Hubbard, to whom Colonel Rohrbaugh has been cared for since the death of his wife.
His Many Benevolences
The name of Rohrbaugh has been so closely associated with improvement in Ottawa that is scarcely needs be said what Colonel Rohrbaugh has done for the town. The opera house is a monument to him. The corner stone on the new M.E. Church attests the fact that he made the church possible, with his gift of $20,000. The following buisness buildings hear his name: Boston store building, fifty-foot front, three stories; Kaiser drug store building, two stories; Miller drug store building, three stories; Nelson State Bank building, three stories. The new residence property on Hickory street was completed a few months ago, at a cost of about $20,000. Colonel Rohrbaugh also owned several other residence properties on Hickory street in addition to the lumber yard.
The Contest Over The Property
That a long litigation will ensue, over the disposition of the property, it is easy to foresee. This controversy had been in probate court in a move to have a guardian appointed for Colonel Rohrbaugh, on the contention that he was of unsound mind and incapable of attending to his property. The first jury disagreed, and the matter had now reached the supreme court, in the form of a mandamus proceeding to compel the county clerk to draw a new jury. It is probable that this proceeding will now be dropped, since there is no longer any requirement for a guardian, but the main issue, as to the condition of Colonel Rohrbaugh's mind during the past few years, remains to be decided in the disposition of an estate variously valued at from $150,000 to $200,000/
When the proceedings were begun in probate court recently, at the instigation of several gentlemen of the membership of the M.E. Church, deeds were filed in the recorder's office, transferring to Mrs. E.P. Hubbard and the members of her family practically all the real estate holdings of Colonel Rohrbaugh. The transfer of this property would nullify most of the provisions of the will, made a few years ago, by which latter instrument the Firt M.E. church, Bethany hospital and Baker university were made large beneficaries. By the will, Mrs. Hubbard recieved one of the Main street drug store buildings, another went to the maintenance of the choir of the First M.E church, and the boston building went o the two outside methodist institutions. The opera house went to S.R. Hubbard and Miss Hubbard. An action to restrain the taking possession of the property transferred by the recent deeds is expected to be the first move that will begin a court contest between the interests at conflict, and which will finally decide whether the will or the deeds shall dispose of the property.
