    On each of these items above I have tried my best to give credit to the author or the holder of the copyright.  If there is one in there in which I didn't, and you know who deserves credit please let me know and credit will be given.  Please realize I am not the author of any of this information, I simply compiled it to save researchers time and effort in the library.  If you have any info I don't and are willing to share I would like to add it here.

    Keep checking back as I will update it all as I find new info.
