Question

What's the maximum amount of people that can be on a single family tree?

Answer 1

It depends on the servers (Family Echo) and the client (you), I guess. If you are able to handle only 300 people at once without it crashing, that is fine. If you can handle 1000 people without it crashing, that is fine as well.

Answer 2

Someone can probably give an official answer, but I can offer that I have 585 people in my family tree right now and have not noticed any change in performance. There are people on Family Echo who have over 10,000 members in their tree. Note that there is some upper limit. From the FAQ:

Q: Why can't I add more distant relatives?

There is a limit on which relatives can be included in a tree, based on their distance from the tree's founder. This limit helps ensure privacy for family members, and prevents the tree from growing indefinitely. If you reach the limit, click the 'Create new family' button to start a new family branch from the selected person.
