Twenty Trees is an online resource for people who are interested in history. It started as a way to categorise our photographs and grew into providing Family Trees, Biographies, Categories, On This Day in History, etc.

Family Trees can be Paternal, Maternal and Descendants. Paternal Family Trees, the ones we traditionally see, trace the Y-DNA that is passed from father to son. Maternal Family Trees trace the mt-DNA that is passed from mother to daughter. Descendants Family Trees show a person's descendants to six generations - limited since some families become vary large.
