I've made various previous attempts at working on my family tree. Every time I get only so far before I get bogged down in all the branches and confusing questions about whether this person was married to that person. So I've decided to start yet again. And to see if by keeping a log of it, maybe this time when I get confused I will be able to backtrack. I suppose we'll see. I suppose my family tree has to start with me?
