1.  Kentucky: County Marriages, 1797-1954 (online at familysearch.org):

Name	James L Jordan		James L Jordan
Event Date	bond: 8 Sep 1873 marriage: 9 Sep 1873		12 Feb 1885
Event Place	Mercer, Kentucky		Mercer, Kentucky
Father's Name	Isaac Jordan (consent for minor)
Spouse's Name	Mary L Jenkins		Lula Gallagher
Spouse's Father's Name	G.H. Jenkins (consent for minor)
GS Film Number	192267		551312

John was only 20 years old when he married Mary JENKINS, so it's unlikely he had a prior wife.  If Lula was his 3rd wife (as indicated in the 1910 census), then he had a second wife between Mary and Lula, but I can't find another marriage record, and there's no intervening census record.

2.  1860 U.S. Census Every-Name-Index/Images (online at Ancestry.com):  can't find a James JORDAN with a father, Isaac.  Mary L. JENKINS (æ 3, b. KY) is living in Mercer Co., KY (p. 655), with her parents, G.R. JENKINS (æ 31, b. KY) & Sarah E. (æ 26, b. KY), plus siblings.
