BROWN, HERRON It was with deep sorrow we learned of the early death of D. W. BROWN, Esq., of Canonsburg, which took place on Saturday night, the 9th inst., at Mercy Hospital, Pittsburg. The disease which took his life was pneumonia, from which he suffered for about three weeks. David was born about 45 years ago in Allegheny county. When quite young, his mother, who was a sister of the late Cornelius BORLAND, died. Soon after this his father, the late David BROWN, move to the farm (in) Mt. Pleasant township on which M. B. BROWN now resides. Her David was brought up, working on the farm in summer and attending the district school in winter. During the winter of '59 and '60 he was a pupil in the school taught by the writer. He was bright, manly, generous, and very fond of fun, which, we believe, were characteristic of during life. Not being enamored of farm life, he set about preparing himself for a professional life. He attended Monmouth College at Monmouth, Ill., and graduated from that institution in the class of 1837. He afterward took a course in the law school of Harvard, where he studied and was admitted to the practice of law at Washington. For a time he was with the late W. O. CRAWFORD, Esq., of Pittsburg bar; then for a while he was associated with L. MCCARRELL, Esq., of the Washington bar, but for several years past he was located at Canonsburg, where he enjoyed quite an extensive practice. He took great interest in the politics of his day, and was prominent in the Democratic party in this county. He was that party's candidate four or five years ago for district attorney, but was defeated. He was popular and successful as a stump speaker, and his voice was often heard during the recent campaigns in behalf of Democracy and its candidates. During the late non-partisan amendment campaign in this State, although he was a Democrat, he made numerous speeches in behalf of the Prohibition amendment. He believed Prohibition would promote public welfare and thereby temptation to intemperance would be in a great measure be removed from the young and rising generation. His voice will no more be heard hear, for the shaft of Death has struck him, and ... He leaves two brothers and ... *Remainder torn off **The date of his college graduation has to be off considering his age at death and the time mentioned as having been the writer's pupil. At Mansfield, on Jan. 12, Mrs. Michael HERRON. Deceased was the wife of Mr. Michael HERRON, formerly of Barr street, and well-know to all McDonald people. Last spring a child of this family was burnt to death in a Laurel Hill coke oven. Mrs. HERRON on Monday morning started to attend a funeral, and while waling on the railroad track slipped and fell and received the injuries from which she afterwards died, giving premature birth to a child.
