William Miller (1795-1878) was the founder of Miller County Missouri, William's son, Pinckney S. Miller (1827-1912) was the first male white child born in Miller County and for whom the county was really named for, The county was first organized in 1836, William Miller took a petition signed by the locals citizens to Jefferson City to get Miller County turned into a real county. William Miller thought they might not want to name it after a local farmer so he got it named after John Miller the governor of Missouri instead. But it was really named after William's son Pinckney Miller. William Miller's house was used as the first court house and for all the county business. Jonathan Milton Houston built the original Tuscumbia Court House for $500 Dollars.
