You said: "PS. I do like your recommendation for the option of restructuring reports along ancestral lines (small letters). The value of such a suggestion might be more evident to the community if someone were to make a sample of how such a report would be organized."
One place to look is the next time you are browsing published genealogies in a library. There will be "descendants of" and "ancestors of" type books. If you pick one out that says "ancestors of", chances are it will be a line chapter by line chapter presentation, not an ahnentafel register reports. Although an ahnentafel table (table meaning bare-bones one line per ancestor - another addition FTM could make) may be included in them for reference.
Another is example no. three in the first link you gave explaining the numbering system - that of the White Family.
Another is the link I posted earlier.
Another is this link - look at the table of contentshttp://books.google.com/books?ei=X_aXUMG6DK2I2gX27oHYAw&...
One of the lines is the Lane line, p 148, Which shows, for example this direct line descendant presentation down to the female that married into a paternal line and a page number cross reference to where she married in - note one could use the numbering system provided in the article you gave - but this format has been used at least a couple hundred years without a numbering scheme.http://books.google.com/books?ei=X_aXUMG6DK2I2gX27oHYAw&...
William1 Lane was a resident of Dorchester, Mass., as early as 1635. He came from Norfolk Co., England. In his will dated Feb. 28, 1(550, he gave his sons George and Andrew £8 apiece. He died 1654.
* George2 Lane, son of William,1 was among the thirty proprietors of land in Hingham, and Sept. 18, 1635, drew his house-lot of five acres, situated on the main street, now North street. He had ten shares in the 1st, 2d, 3d and 4th Divisions, ten acres at Nutty Hill, and thirteen acres in common lands; selectman 1669 and 1678; freeman Oct. 8, 1672; died June 4, 1689. In 1680 he had assigned to him in the old Unitarian Church "the seate under ye pulpit," and his wife, Sarah Harris, daughter of Walter and Mary # (Fry) Harris, had assigned to her "the fore-seate for the women in the body of the meeting house." She died March 26, 1694-5. Walter Harris came to Weymouth in the ship "William & Francis" 1632, lived there twenty years, died in Dorchester, Nov. 6, 1654. His wife died Jan. 1655.
Ebenezer3 Lane, baptized Aug. 25, 1650, son of George2, married Dec. 27, 1688, Hannah Hersey, born in Hingham, Feb. 13, 1668, died March 31, 1745, daughter of William and Rebecca (Chubbuck) Hersey. "Ebenezer3 served with distinguished bravery in Capt. Joshua Hobart's Co. in Philip's Indian War, Oct. 1675, and was on the roll of Capt. Isaac Johnson's Co. of Roxbury, Dec. 13, 1675, which enlisted for the Narragansett campaign of July, 1675. He died Dec. 12, 1726, aged 76."
Susanna" Lane, daughter of Ebenezer3, married Dec. 31, 1724, Jonathan Studley. (Line continued on page 45.)"
I can see where this would take a bit of programming to get done and probably take more memory than the current only option - the ahnentafel register report - but I think it is so much clearer to read for a reader.
