Just thought I’d drop you a note regarding name changes through adoption, etc. You CAN actually add another set of parents to a person with Family Tree Builder. The program then offers you a choice of detaching that individual from the parents already listed, adding new parents as those adopting this person or adding them as the biological parents with the already listed parents being noted as those adopting. You can also click on ‘Names’ in the editing area of an individuals listing and add a second set of names (and possibly more if need be – I’m not sure of this as I’ve not needed the function.) On the chart, the current name will be shown with Former Last Name (in the case of an adopted child perhaps) shown directly below.

I hope that wasn’t too convoluted a ‘tip’ and that it helps with your character creations!
