JACOB SEIF, farmer; P. O. Gabon. The history of Morrow Co. would be incomplete without a sketch of Jacob Seif, whose successful career has justly entitled him to a place among the self-made men, and whose present surroundings are due to his industry and business tact. He was born August 21, 1816, in Baden, Germany; his father’s name was Jacob, and his mother’s maiden name was Margaret Cronenwett; his father was a shoemaker by trade, and made that his occupation, although he worked some on the farm; he emigrated to this country in 1829; his reasons for coming were to save [his children from the regular army, and to better his own circumstances in life; he settled in Columbiana Co., Ohio, where he remained for two years, when he moved to what is now Morrow Co., and entered eighty acres of Government land, which was ever afterward his home; he worked on the farm part of the time, and would sometimes make shoes for the neighbors while they were clearing his farm; he was a very industrious and frugal man, and died in 1840. The subject of this sketch lived under the parental roof until his 24th year, when he married, which was Dec. 18, 1839, to Sophia Neyer; she was born Apr. 7, 1817, in Pennsylvania; they had twelve children, eight of whom are living — Jacob, Solomon, Elizabeth, Aaron, David, Adam, Christine and Caroline. Mrs. Seif died Sept. 1, 1873; Mr. Seif is a member of the German Methodist Church, of which he has been Steward for twenty-five years; has been Trustee a number of years, and was
Land Appraiser in 1870; he is one of the few Germans who ally themselves with the Republicans in this county, having left the Democratic party during the agitation of the slavery question.
