Too many inconsistencies to say there is a connection but also too many coincidences to write it off. Hope this helps.

Carroll Co. AR Biographies http://searches.rootsweb.com/cgi-bin/ifetch2?/u1/data/ar+index+4008893777+FHiram S. Shahan, an enterprising farmer, and the present sheriff of Carroll County, Ark., was born in Preston County, Va., September 15, 1837. He is a son of John S. and Nancy (Thorn) Shahan, both also natives of Preston County, Va. About 1841 John S. Shahan removed west with his family, and settled in Carroll County, Ark., on pre-empted land. Here he improved a farm, on which he still resides. His wife has been dead several years. For a number of years he has held the office of justice of the peace, and is a stanch Republican in politics. Hiram S. Shahan grew to manhood on his father's farm. In 1861 he enlisted in the Union army for three months, which time he served in the Home Guards in Missouri. On July 7, 1862, he enlisted in the regular service, and was assigned to the First Arkansas Cavalry, with which he served until the close of the war. During the battle of Prairie Grove he had the thumb of his right hand shot off. A shot also passed through the sleeve of his right arm. Before the war was over he was promoted to quartermaster-sergeant. When hostilities ceased he returned home and engaged in farming. He was married in Carroll County, in 1859, to Amanda E. Litterell, a native of Alabama, who was chiefly reared and educated in Carroll County. To their union have been born ten children, of whom John M. and Matilda Jane are deceased. Those living are Grant (of Kansas), Nancy (Mrs. M. Bridwell), Hiram L., Elijah, Charles, George, Clara and Effie E. Both Mr. and Mrs. Shahan are earnest Christians and members of the Methodist Episcopal Church. Mr. Shahan is a member of Green Forest Masonic Lodge, and is a Master Mason. In politics he endorses and supports the principles of the Republican party. For four years he served as justice of the peace. He was also appointed assessor, and made one assessment of the county. In the fall of 1886 he was elected sheriff of the county, receiving a majority of ninety-five votes, when the county is Democratic by a majority of 400 votes. He has made a faithful and efficient officer, and has given satisfaction to both parties.
