I have done a little research on Eliza J. McElyea, daughter of William Carroll McElyea and Lavinia Neal.
She married Jonathan King August 13, 1872 in Cherokee County, TX. They had four children. James Madison King, b. 2/18/1874 d. 1/20/1955 William King, b. 1876 Vinie Mary King, b. 2/11/1880, d. 5/5/1964 in Lamesa, Dawson, TX. John Calvin King, b. 6/20/1882, d. 8/5/1943
Eliza died between 1882 and 1885. Jonathan remarried to Mary Douglas September 5, 1885 in Cherokee County, TX. They had at least one child, Sammy (Samuel?).
James Madison King was married to Fannie UMN (unknown maiden name).
Vinie Mary married Thomas Lee Wallace.
John Calvin King was married to Nellie Stockton.
I don't have any info on William King.
I have seen Jonathan's name as John, Johnson, and John Horton King.
Their son, John Calvin, was not married to a McElyea.
Mary McElyea, daughter of W.C. McElyea and Lavinia Neal died before 1860 and was only about 6 years old when she died.
Hope this helps. If I can answer any questions, please email me directly at email@example.com.
