Yes it worked

after moving to the standard pedigree tree
view

then I clicked on the Genealogy Report button

then the Menu > Format > Genealogy Report

which gave three radio buttons as choices
# Register (Descendant Ordered)

The Register format dates back to 1870 and is used to establish "pedigree."

# NGS Quarterly (Descendant Ordered)

The format dates back to 1912.

# Ahnentafel (Ancestor Ordered)

but when by who ?

The system was first used in a book by the Spanish geneologist Jerome de Sosa in 1676.

AHNENLIST
a list of one's accordance with the AHNENTAFEL Numbers definition below. ancestors, with the first generation being #1, second #2-3, third #4-7, etc. May be synonymous with AHNENTAFEL.

AHNENTAFEL
[German ancestor table] a list of ancestors numbered in accordance with the system described below in AHNENTAFEL Numbers. So-called because it was popularized by Stephen Kekule von Stradonitz in his 1896 book, Ahentafel Atlas.

The system was first used in a book by the Spanish geneologist Jerome de Sosa in 1676.

Translated from the German, "ahnen" means ancestor and "tafel" means table or list; because of this literal translation, ahnentafel is sometime incorrectly used to describe any list of ancestors. - Richard Pence -- richardpence@pipeline.com.


AHNENTAFEL Numbers
the universally used method of numbering ancestors.

In it the number 1 is assigned to the subject of the list, then his or her father is No. 2, the mother is No. 3, the paternal grandfather No. 4, etc.

In this system, a person's father's number is always twice the person's number and his or her mother's number is twice-plus-one.

Because of the structured nature of the sytem, a person's ahnentafel number can be used to describe his or her relationship to the subject of the list.

This method of numbering ancestors is used worldwide and is also called the "Sosa-Stradonitz System," after the genealogist who first used it and the one who popularized it (see AHNENTAFEL above)

. This method of numbering ancestors is used both on lists of ancestors or on ancestor charts. - Richard Pence -- richardpence@pipeline.com
