Milldale Colored School (Covington, KY)
Very little is known about the Milldale Colored School. In 1883, there was a one-sentence notice in the Daily Commonwealth newspaper seeking a teacher for the Colored school at Milldale [see article "The City, p. 2, col. 1]. This may or may not be the same school that is listed in the Williams Covington and Newport Directory for 1890 and 1892.The school, located on Williamson Street in Milldale, KY, was one of the primary schools for African American children found throughout Kentucky. In 1890, Martha Butler was the teacher, and in 1892, Susie Taylor was the teacher.
Milldale, previously known as South Covington District, was classified as a 5th class city, then unclassified in 1896.
