Read Descendancy

Read the descendancy of a person for a specific number of generations. The result of the query provides a list of persons. Each person will supply a descendancy number in the display properties for the person. The descendancy number is interpreted as a d'Aboville number which can be used to determine the position of each person in the descendancy.

The descendancy query supports the inclusion of the spouses of each person in the descendancy graph. Spouses returned in the query will also have a descendancy number, but the descendancy number will have a -S<#> appended to indicate the role of spouse. The '#' indicates the spouse number.
