GeneWeb
GeneWeb is a program that I mainly use to show relationships
between my relatives.
The program can show the connections between persons graphicly, eventhou they
are related thru marriages and relations to the spouses family members.
I import data frommy DISGEN database via a GEDCOM file, this works very well.
The program can do may other things that I don't use. It is simple to install
and run localy on your PC for your own use or to install on a server for
use over Internet. The server installation requires, as far as I know, that you
start two services on the server.
