Help for the Ancestor Longevity Report

For an individual's data to be part of this survey, GRanDMA must have both birth and death records. The dots in the report indicated that, while the name of that ancestor might be know, either birth or death data are missing.

The report shows the lifetimes of each ancestor where the data are available. A dot represents individuals for whom we do not have sufficient information.

Hover over any lifetime, and the name of the individual will be displayed.

The chart provides the distribution of ages. Again, hover over a bar, and the identity will be displayed.
