Gillespie/Ewen/Sparks/Collier from Kentucky Page

I am researching families from the Kentucky, Virginia and West Virginia area with the names Gillespie, Collier, Sparks, and Ewen.
I also have names French, Walker, Osborn, Roberts, McLaughlin, Stephens or Stevens, Whitt, Kelly, Morris & Steele.

I have a database with about 300 names, but am stuck on trying to locate children of an Elsbery Gillespie with his second wife, (1st wife Georgeann Stevens) Bettie or Billie Parmer, married 1887 in Kentucky, but I lose them after 1890. I think they had a son who may have gone to Michigan to work.

I would love any information or assistance you might have and I would be pleased to share information that I may have if any of the names above are in your family tree.
