Senk and link to Dunbaker

I am trying to track my lineage with very little info. We have some connections to the SENKS and most of my family was in PA, WVA, and VA. I know I was a Dunbaker,...Maude being the great grandmother, her son- John Walter Dunbaker, married Olive ?? had children Walter Wayne Dunbaker and Darlene Dunbaker (who is now a Gilley).I know my father walter Wayne Dunbaker married brenda Lee Mulkey.If you have anyfurther information I would greatly appreciate it.I also know that supposedly on the Mulkey side we are of Cherokee decent, and on the Senk/Dunbaker side of German/English decent.
Looking forward to ANY response.
Sincerely,
Lost child
