When using these Tree links:

If you click 'Home Card' you will be presented with a pre-selected Family Page.

To step backwards in time, click on a parent's name at the top of the page, or to trace descendants, click on a child's name.
Click on the name of an individual in the middle of a page to see his/her personal page, which contains more detailed information, and from which you can follow through to find ancestors or descendants as before.
Where there is more than one spouse, click on the number to switch to detail of that marriage.

You can return to the title page, or other sections by clicking at the foot of any page you are on.
