Diana Williams of Dallas, Texas, is a long-time Walling-family researcher. She has been studying the Wallings and related families for decades. I have been fortunate enough to have visited with her on several occasions. In 1998, She was kind enough to provide me with a copy of some of her research stored in the form of a Family Tree Maker(tm) file. I promptly printed a report from that (it is 41 pages long) and use that hard-copy as my source reference when referring to her work. It's much easier and more precise that way than trying to pinpoint facts inside computer files, which are notorious for changing. I've not heard from Diana in some months, but earlier this year she was still hosting the WALLING-L mailing list sponsored by rootsweb.com. It's free to subscribe to that and it can be a very helpful source of information. At least it has been for me.
