A look at my chart of ancestral places of birth makes it appear that my parents and grandparents lived in Iowa, at least for a short time. That’s not true.
Charts can sometimes be misleading.
The reason my parents were born in Iowa is because that’s where the nearest hospital was located when they were born. No one ever lived in Iowa. But that is where they were born and that is where their birth certificates are recorded.
When using or creating any chart, be aware that it can have limitations.
