Tell anyone your hobby is researching your family tree, and one of the most common responses is ‘How far back have you got?’ Here is my answer to that question.
On all of my lines, I have gone back at least 4 generations, i.e. to my great-great-grandparents. Going further back depends on many factors, but I have found that the most important is whether a family stayed in the same area. The line I have provisionally got furthest back with stayed in one village for 6 generations, about 180 years!
