Nearly all English Ivalls are (like me) descended from James Ivall (1745-1809). I have recently updated my family tree on RootsWeb as part of their WorldConnect project. If you click on
http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=SHOW&db=philt42lqs&recno=833 it should take you to a list of Ivalls descended from James. If you click on a name on this list, a page showing the person's parents, spouse and children will be displayed. You can navigate up and down generations from here. The names of living people are not shown.
