Everything I have on the Parker's and Ford's is on my website Mercer Family History located at http://mercerfamilyhistory.comhttp://mercerfamilyhistory.com
There is now almost 60,000 people in the database tied in those tree's. There are four of us that work on the site. We have received documents, pictures, cd's, gedcom's etc. from numerous researchers of these two families from all over the U.S. and some foreign countries.
We have full subscription's to Ancestry.com linked with our Family Tree Maker Software to search for information.
Our database is updated on a regular basis to Ancestry.com, Rootsweb.com and GenCircles.com.
We belong to several mailing list's on surname and county message boards.
Since William and Elizabeth (Ford) Parker are not in my direct line I really don't have the time to spend to track down anymore information that what I have on them.
I would be happy to put any information you find on my website though.
