Yes, I'm a McGlothlin descendant. Here is my lineage:
Frieda Patrick Davison
daughter of Clyde Anderson Patrick and Beulah Marie Rasnake
Son of Charlie Scott Patrick and Nannie Belle McGlothlin
Daughter of Frederick Yance McGlothlin and Armelda Monk
Son of Frederick Arthur McGlothlin and Louisa Samples
Son of Jacob McGlothlin and Elizabeth (Betsy) Clark
Son of John McGlothlin (Rev. War Soldier) and Judith Leathers.
John was a brother to Jacob and Stephen McGlothlin - also Rev. War Soldiers.
Jacob was the father of your Cornelius.
Also, I was the editor of the book The Honaker Family in America that was published in 1998. It is 1,400+ pages.
Let me know if I can help with anything else.
