I belong to www.myheritage.org which is a free site & have printed a few charts for whanau & friends. Coloured & laminated with photos, dates, places etc., mine are 6 feet wide, beautiful taonga. You can find photos, dates etc. on there if someone else shares some of your tipuna, a green icon comes up saying Smart Match. Then you can review the match, compare & edit yours directly from theirs.
