One thing that creating the various pedigree charts has reminded me of is that I think I know more than I actually do. The drafts of the charts have been created from memory and there is usually at least one factual error in each rough draft.
It makes me wonder, “are there other times when I’m searching that I’m operating under premises that are not true? Do I have something in my head wrong that is making it more difficult for me to find someone?”
Try creating one of the charts of your own based on memory. Then check it with your records. You may be surprised at the results.
