On June 8, 1826, about two months after the patents for his land in Illinois was issued, Zachariah sold the east half of the south east quarter of section 12, Township 13, Range 13 to Thomas Cowhick for 101.50. (This represented a profit of $1.50 for that 80 acres based on the assumption that he paid $1.25 per acre to the government for the land.)

This was about six months after he sold his 73 acre farm in Kentucky to James Pace on September 20, 1825, for $900.00. It is likely that he used part of this money to pay for the land in Illinois ($360.00) prior to the issuing of the patents on April 3, 1826.

It should be noted that the sale of this land occurred about 5 months before his death. There is controversy over where he was buried. DAR records suggest that he was buried on the farm he sold to James Pace in Clark County, Kentucky. Other sources suggest that he was buried in the old Bethlehem Church Cemetery, also in Clark County, Kentucky. However, both seem unlikely for the following reason:

Zachariah had undoubtedly entered the land in Illinois about three years earlier and had to travel to Clark County, Kentucky, in September of 1825 to sell his farm in Kentucky to James Pace. He then returned to Illinois to make the appropriate payment for his land at the land office in Edwardsville, obtain the certificate showing ownership and subsequently sell 80 acres of his land in Illinois, probably to raise additional funds for improvements to his land in Illinois. It is hard to believe that Zachariah would again leave his home in Illinois to return to Kentucky so soon.
