If you have a family listed here then you can send in whatever additions and corrections you want - providing you would be happy to see them on the web.
This means that other family history researchers will be able to find your family details via the popular search engines (Google, Yahoo!, etc). And your family tree is available on the web without any cost to you or the other researchers.
Simply send the information - as text or as a Gedcom file via email.
Pages will be updated within a month of being received.
