Up to 15 children may be entered per relation. If this causes you problems, please write.
Like the Parent fields, these fields either start a new link, or finish a link started by clicking on the "To Parents" button on a People card.
If the card has a name in it, clicking on the card will go to that card. Pressing the shift key will go to that person's children (by their first marriage) if there are any, bypassing the People card. Pressing the option key allows you to change an existing link.
For twins, triplets, etc. use the painting tools to change the branches to angled branches from a common root.
