Betty,
I have been researching this family as well. Thomps White and Margaret are also my great great grandparents.
My line is through their son George.
I have been told that the parents of Thompse are JOhn White 1830 1896 and Sarah Worley 1832 1899. They are buried at the Rebird Cemetery in Whitley. John's father was Nicholas White.
I have apicture if you are interested , I will be glad to email if you are interested.
Email me. Maybe we can share.
Brenda
