LEWIS SPEAK, born in Nelson County, Ky., Oct. 15, 1815, is a son of John 
Speak, an early settler of that county.  He was educated in the common 
schools and in St. Mary's College, Marion County.  He was reared on a 
farm, and has always followed that occupation, now owning a farm of 100 
acres.  He came to Daviess County in 1850, and has since resided in this 
precinct, with the exception of one year spent in Yelvington.  He 
married Frances M., daughter of William Medcalf.  Nine children have 
been born to them--Mary, John T., Sarah, Matilda, Rebecca, Martina, 
Henry, William and Emma.  Matilda married Zachariah Head, and died Jan. 
21, 1883, leaving two children.  Mr. Speak is a member of the Catholic 
Total Abstinence Society.
