Clinton McKamy Winkler was a lawyer, judge and a member of the Texas Court of Appeals for many years. He was born in North Carolina in 1821 to David Tate and Lavinia Cates Owen Winkler. He moved with his family first to Indiana in 1835 for a few years before relocating to Texas in the early 1840s. They settled in what is now Robertson County to be near other Winkler relatives. The family was said to be descended from German immigrants, but his grandfather was born in North Carolina according to traditional genealogical sources. McKamy was also an old family name and many of these McKamy relatives were also residents of North Carolina.
