I checked the tax lists for Purdies & Trents. Based on a cursory analysis of the tax lists of early Patrick County, it appears that Zachariah Trent is likely the son of Field Trent who may be the son of Elijah Trent. There is a James Purdie in the tax lists, you might try looking for his will. James appeared to have sons Caleb and Ezekiel. Randy Crouse McNew Huntsville, AL
