Mary Jack, third daughter of Patrick Jack, of Charlotte, married Captain Robert Alexander, of Lincoln county, who emigrated from Pennsylvania to North Carolina about 1760. He commanded a company during the Revolution, in the Cherokee expedition, under General Rutherford; acted for several years as Commissary, and performed other minor, but important trusts for the county. He was one of the early band of patriots who met at Newbern on the 25th of August, 1774, and again attended the Convention at Hillsboro, on the 21st of August, 1775. After the war, he settled on his farm, one mile northwest of Tuckasege Ford, on the Catawba River. His residence was long a general stopping-place for travelers, and painted red--hence, it was widely known as the "Red House Place."
He was elected to the State Legislature consecutively from 1781 to 1787; and acted, for many years, as one of the magistrates of the county, showing the general acceptance with which his services were held. He died in 1813, aged about seventy years, and is buried in Goshen graveyard, Gaston county, N.C. His descendants by the first wife, Mary Jack, were: 1. Margaret, married Judge Samuel Lowrie; 2. Lillis, married Capt. James Martin; 3. Robert W., married Louisa Moore; 4. Mary, married, 1st. James J. Scott, and 2nd. General John Moore; 5. Annie, married John Sumter, (nephew of Gen. Sumter.) His descendants by the second wife, Margaret Reily, were: 1. Eliza 2. Evaline; 3. Amanda, married Dr. J.C. Rudisill, of Lincolnton.
