Frequently asked questions

How does the ancestor timeline generator estimate birth years?+

It calculates the average gap between the birth years you enter for your known generations, then projects one additional generation back using that same average gap, not a fixed 25 or 30 year assumption.

How many generations can I enter?+

Between 2 and 10 generations, from your own birth year back through as many ancestors as you know.

How accurate is the estimated generation?+

It's a reasonable estimate based on your own family's actual generational spacing rather than a generic guess, and it's clearly marked as an estimate in the timeline.
