I just found this on the profile of a Peter Troxell of Lehigh Pennsylvania. But it's clearly referring to a Maryland man (Frederick County is in Maryland). It includes reference to a Jacob who died intestate in 1799 (so not our Jacob who died in Alabama in 1843).
Jacob Troxale, son of Peter – Frederick County
15 June 1790, resurveyed tract called “The Resurvey on the Resurvey on William’s Pleasure” in Frederick County, originally granted 19 August 1771 to John Shrior (sic) 692 ¾ acres. Land called “Haspewele (Hopeswell?), died intestate, leaving petitioners, John, Elias, Mary intermarried with Joseph Stevenson, Peter, Catherine, who intermarried with Elias Grashon/Groshon, Jacob, Magdalena, Susannah, Amelia Troxall (sic), his only children and heirs at law.

Jacob Troxall – Frederick County
Certificate for “Hopewell”, 202 acres in Frederick County. Jacob Troxall, son of Peter, of Frederick County, tract called “The Resurvey on the Resurvey on William’s Pleasure”, originally 19 August 1771 granted John Shrior for 692 ¾ acres. MD LW&P 1814-1818, FHC Film 0013134, page 643.
