Ah, the plot thickens!I hadn't heard of this Hardy Allard before, but they do sound like relations.Aaron Hardin Allard wasn't born until abt. 1801.His descendants tell me he moved from (Madison Co.)IL to TX in 1842.There are a number of active TX Allard researchers, so I'll leave it to them to expand further.
Aaron Hardin's parents were David and Mary Burleson Allard. "Aaron" after her father, "Hardin" after his father I assume.I have records placing Hardy and Sarah Allard in Warren Co., KY in 1802 and 1805 and then in Pope Co, IL in 1816 along with David.
Does anyone know if David had an older brother who could be father of this Missouri legislator?
