Leonard and William Mattingly were sons of John Mattingly and Sarah Wheatley. William Mattingly and Barbara Spencer were two of my 3rd gt grandparents and I'll be happy to share what I can. I maintain a lot of my data on Rootsweb of Ancestry.com and if you go to <www.rootsweb.com> and run a search for one of the names you've listed you'll find that data under the file name of Cezar. Be glad to send you the file if wanted and would appreciate learning from you as well. I lose a lot on Leonard's line and have run across no descendants as yet. Hope you are one.
