GeneaNet: Set Your Online Family Tree Root
An Ahnentafel is a genealogical numbering system that allows one to list a person's ancestors in a particular order. It is also known as the Sosa-Stradonitz Method. In an Ahnentafel each person's father is numbered twice that of the person. Each person's mother is two times that person's number plus one.
You can easily set your GeneaNet online family tree root and automatically list your ancestors.
Basic Edit
Click "Modify Individual" in the box of the selected person, then click "Define as Family Tree Root" to set the person as your family tree root
Expert Edit (GeneWeb)
Log on to your online family tree as "Wizard", then select an individual and click "Update - Individual/Family". This will open a window that shows you a list of available update options. Click "Set to home individual" to set the selected individual as your family tree root.

Sosa numbers will be automatically assigned to your family tree root ancestors.

If needed, you can deactivate the numbering system. Select the "Online Family Tree - Manage - Expert Options" menu item then click "Remove the family tree root". Note that this will not remove the individual in your family tree!

Is there an update??
