All the genealogies tell the same story about our ancestors Daniel and Nancy. They arrive in Wayne County, MS in 1819 and are found on the census in 1820 in Wayne County together with Nancy's parents John Calhoun and Effie McLaurin Calhoun. Either in September of 1820 or in September of 1821, Nancy, her parents and the baby, Daniel McLaurin, III die. We don't know what from for any of them. I've never been able to track down where the graves might be for these pioneers. In an effort to try to track it down, I turned to the history of Wayne County itself. Here we learn that Wayne County used to be much larger than it was and it's likely that Daniel did not arrive in Wayne County and then in a couple of years move on to Simpson County. It's more likely that where they lived became Simpson County.
Here's a bit of the history from the Wayne County Historical Society:
In 1809 the county of Wayne was organized by Legislative act with its present northern, eastern, and southern boundaries, but extending westward to Pearl River. One county after another was organized, taking off portions of Wayne's territory on the west until the organization of Jones county in 1826, when it took its present western boundary.
Many highly refined families, some of which owned a large number of slaves and live stock, came from Virginia and the Carolinas to find homes in the wild southwest. Among the early settlers of Wayne county were the McRaes, McArthurs, McDougalds, McLaughlins, McDaniels, McDonalds and McLaurins. The constantly recurring "Mc" in the list of names tells whence they originally came. They not only brought with them the sweet language of their beloved "Scotia," but brought as well that Scottish simplicity which Burns so beautifully portrays in his "Cotter's Saturday Night." They were a hale, happy and industrious people, conservative in all things and inclined to make the best of existing circumstances. They loved culture and refinement and established schools and churches without delay. A number of those Scotch people settled on Buckatunna Creek not far from the place now known as the Philadelphis Presbyterian church. It seems that a line of settlements were made along both banks of Buckatunna Creek and Chickasawha River. From careful observation the writer has noticed that all the early settlements were made near the larger streams of the county, often almost on the banks. There must have been two reasons for this, the fertility of the swamp lands and the facilities of water transportation. The most important early settlements in the county were at Winchester, the first county site, and at the Scotch settlement on Buckatunna creek. The Scotch settlers built the first church and established the first school in the county. They were accustomed to call their American neighbors "Buckskins," which is a survival of the term applied by the British to the colonial troop in the old French and Indian war of 1755-63.
The first school was established about 1812. The Gaelic language was spoken exclusive among the settlers, and was also taught in their school. This language remained the vernacular until the early 20's, when other settlers arrived, some of whose children knew English alone. For the sake of the English speaking children the teacher then forbade the further use of Gaelic in the school room. Having been discarded in the school, the Gaelic language soon fell into disuse except to a limited extent among the older people. To this day [ca. 1902] in that neighborhood the Scottish pronunciation of such words as "said" (sade) is frequently heard.
