Ok, it wasn’t a FAQ that I remember, it was in my email… I’ll add it as a QuickTip, but here are the instructions:
Say we have a family, the Doe’s.
First, lets start with one of the parent’s, John. Create a new Individual entry for John and put in all his personal info.
Second, simply copy John and change the first name to Jane and add/change any info that relates only to her. For example her birthday.
Third, do the same for Girl and Boy.
Now create a new entry using the Family entry type. For the Family name enter something like “Doe, John & Jane” and then click the “Add Relation” button for each member in the family, in this case four times. In the first column of dropdowns select each family member and in the second column of dropdowns select their relationships.
Hope that helps!
