Re: Julius T. Aurin b. 1844 Germany
Julius is proably the same as Jul F. Aurin shown on the immigration records, born about 1844 in Germany.Therefore, he is probably son of C.D.(born about 1800) and Catherine A. Aurin (born about 1801).The family emigratedfrom Delfzijl, Deutchland to New York on 24 Sept 1849 on board the "Sarine".Arriving with Jul and his parents, were his brothers, Gustav W. Aurin, born about 1820 (my g,g,grandfather and Civil War veteran of the U.S. Army), and C.A. Aurin, born about 1838; and his sisters, A.B. Aurin, born about 1827 and Marie C. Aurin, born about 1835.
C.D. was a cabinet maker in Knox County Ward 7 in the 1870 Census.
Gustav lived in Morgan County and was married to Martha Jane(Horton??).G.W. died sometime between 1868-1870.
Good luck.Let me know if you find out more about the family.
