Collin County and its county seat, McKinney, are named after one of the first settlers here: Collin McKinney (1766-1861). A land surveyor, merchant, politician and lay preacher at various times in his life, McKinney was born in New Jersey and had lived in Tennessee, Kentucky and Arkansas before he moved to northeast Texas in 1830-31, a time when the area was part of Mexico but under an Anglo-American colonization grant.
And today Collin County is the sixth most populous, and still the fastest growing, large county in Texas. But even with all this change, and with more and more people and businesses moving into the county from other parts of Texas and the nation, we still maintain our ties with our roots through the Collin County Historical Commission and other local guardians of our history.
