There is too little information in this compilation for it to be any more than a teaser for people interested in taking up family tree research. Most people could probably guess that birth, marriage and death records, and census records are an important part of the research process. However, this programme simply states that and does little if anything to give viewers any practical guidance on getting started with their use.
For example Jeremy Clarkson, one of the featured researchers, made a couple of quick appearances in the programme and then just turned up with a huge scroll on which is printed a comprehensive family tree. How did he get there? The programme omits to tell. Don't waste your money.
