GEORGE3 HACKER (Johan Adam2, Christoph1) was the fifth son of Johan Adam and Maria Elisabetha (Weidman) Hacker. He was born 9 Oct 1766 and christened 12 Oct 1766 in the Emanuel Lutheran Church in Brickerville, sponsored by Lorenz Haushalter and wife (his uncle and aunt).  He died 12 Sep 1846 and was buried in the Emanuel Lutheran Church cemetery. 
George married CHRISTINA MILLER, daughter of Christopher Miller and Maria Barbara Stober of Cocalico township, Lancaster county, Pennsylvania, before 1814. Christina was born 1 Jan 1778 and died 29 Oct 1858.[4,5] She is buried in the Emanuel Lutheran Church cemetery with her husband.
I have only been able to locate data on one possible child of George and Christina, as follows:
- JOSEPH4 HACKER was born 3 Jul 1816 and baptized 21 Jul 1816 at St. Luke’s Lutheran Church, Shaefferstown, Lebanon county, Pennsylvania, sponsored by his aunt and uncle Christoper and Anna (___) Miller. He may have married a woman named Susanna. There is a Joseph HACKER in the 1850 census for Elizabeth township, Lancaster county, the 1860 census for Ephrata township, Lancaster county, the 1870 census for Stouchsberg, Berks county, and the 1880 census for the 1st Ward of Lebanon, Lebanon county.
Census records don’t show George until 1810 when he is listed in Cocalico township. He is in Lebanon township in 1820, living alongside Christopher Miller, possibly his brother-in-law. I have been unable to find him either 1830 or 1840 U.S. Federal census records. Christopher Miller, however, is back in Lancaster county, in township in 1830 through 1850.
Lancaster county tax records show a George Hacker in 1791, his status “freeman.” I’m assuming that this is Johan Adam’s son George as Adam’s brother Johan George had moved his family to Erdenheim (outside Philadelphia) in 1763 and Frederick’s son George (Johan George’s nephew) was an infant. He is listed in 1796—1799 tax records together with Frederick, his brother. In 1800, he’s listed separately, but in 1801—1803 they are listed together again. In 1805, George is listed as having 10 acres valued at $600, having 1 saw or grist mill. George, the miller, is also listed in 1806, 1807, and 1808. There my tax records end.
In 1817 George purchased land in Lebanon county with his brother-in-law Christopher Miller.  On 21 Jul 1816, George and Christina had a child, Joseph, baptized in Shaefferstown at St. Luke’s church, and sponsored baptisms at Shaefferstown in 1815 and 1817. In Nov 1817, George sponsored a child’s baptism at Salem Lutheran church in Lebanon.
However, that’s where the trail goes cold. I have nothing on him, including the births of other children, tax records, or land transactions, until his burial at Emanuel Lutheran Church.
