In the show the detectives use a murder board to highlight and focus on the victim, suspects, and any other persons of interest. Donna points out how this concept can be useful to your research as a genealogist. I would agree. I'm a visual person and in the past have used timelines, but I like the idea of expanding upon that. Until your research is arranged in an ancestor board (a.k.a murder board) or timeline you may not spot what you have overlooked. Sometimes a visual organization can point out a gaping hole in your research or give you an idea of some records to look into.
Anyway, Donna goes into a lot of detail in her blog post and I found it very entertaining. Meanwhile, I wonder what my husband would think if I turned a wall of our office into an ancestor board?
