"WikiTree is a great, collaborative, global family tree site for genealogists of every level from every part of the world." —Family Tree Magazine UK, November 2023

"Before WikiTree, I was skeptical and discouraged about big one-single-trees because there were (are) so many errors, but WikiTree is different because it's collaborative, genial and there are people available to help resolve any issues." — Roberta Estes, blogger

"It's been wonderful to experience how collaborative genealogy in WikiTree makes all of us better genealogists. Collaboration on our shared ancestors encourages us to share information and to hold each other to high standards." —Ellen Smith, member since 2014
