Sandra, Thank you for the clarification for LOC. So many people use just an acronym, such as LOC, rather then properly using the definition of the acronym and then use the acronym in the body of the text, so people know what you are talking about, example Library of Congress = LOC. http://www.loc.gov/ I think acronyms are used frivolously, far too often, in our everyday conversation. Having worked for a large corporation, I know everything and anything had an acronym. I would hope that I'm not the only one who would appreciate acronyms be defined before they are used on the list, it may help us all to clarify some terms unfamiliar to people who live in other parts of the country. Violet, thanks for pointing out the information in the title page of a book and how that can aid you to find a book at the LOC, guess I've been doing this the hard way for a long time and this may open many more avenues to my investigations. I have been busy in the past week documenting more information on the Pearson/Pierson line and hope to put this information together and give to the list later in the week. You may find it very interesting. I also have a relative who is temporarily working in Washington D.C., for a period of time, who has been going to the National Archives, trying to find leads on our family ties in Maryland and I have passed the tips that have emerged on this site this week on to him. They were most helpful.Unfortunately, the archives are closed at least until July 5 because of the flooding. Since I an in the mountains of Colorado, getting to Washington D.C. is a hope of mine someday, but not in the near future. I have also found my Dixon/Dickson/Dixson study I did last year and hope to post that too. Dott
