A: As you get further back in your ancestry, it becomes harder to find information on the parents
of your direct line ancestor (direct lines are those parents, grandparents, great-grandparents, etc. that relate directly
to you and are the ones on your pedigree chart). One of the solutions to this often called “hitting a brick wall”.
For example, if your great-grandmother’s death certificate does not have her mother’s maiden name listed, you
may find the name on the death certificate of one of her siblings. This is what we call, “coming in the back door”.
