The correct spelling for our line of the Blacks is Loudon. I know I saw a Pearl now I just have to get back to it. have you ever heard of a book called The Plains And The People? I saw it once on Amazon. it is also in our public library, but you cannot check it out only read it. you can have them make copies for a price. I went once but only had a little time to look at it and will go again when my health permits. in the meantime I am still looking for you keep in touch with me in case i loose you.
