I am tracingmy husand's line and so far begin with JOHN SACK, born 1832in Prussia, married first to ELIZABETH, b. 1828 in Prussia and then to CATHERINA, born 1840 in Hesse-Darmstadt, died 1913.The familywere cigar makers in Chicago(1860; 70 & 80 censuses) and appear to have had some money.John died during the 1870's and Catherine continued the profession. Children by Elizabeth were LOUISE, b. 1854;FREDERICK, b. 1857 and JOHN b. 1859.Children by Catherinewere:FRANK SACK, b. 1865; MATILDA, b. 1867;CHARLES b. 1869;JOHN C.b. 1871.There is a MARTIN SACK in the 1870 census, a policeman, who appears related and is a name that continues throughout John's family from Frank's line onward.Finally, many of these people are buried in Oak Woods Cemeetery in Chicago.Delighted to share what I have.
