Genelines helps by highlighting missing birth and/or death dates with unfilled sections of a person’s life bar. Genelines estimates both missing birth and death dates.In the following example, David Moland has both a birth and death date (i.e. a solid life bar) while his mother, Johanna Webber, does not have a death date. This is depicted by the unfilled section of her life bar which extends to a death date estimated by Genelines. Note also that his father’s record has neither a birth or death date.
