There is a good article by George G. Morgan on this subject in the current Ancestry Daily News (28 Jan) that I found useful. For those interested in reading it, go to this web site (below) and scroll down to the article. If the Jan 28 issue is already gone, or you don't have web access, let me know and I'll forward a copy to you if you like. http://www.ancestry.com/learn/columns/dailynews.htm Carl Cason, Bothell, Washington email: ccason@compuserve.com
