They do not show up in the books in any case. The first, or selected individual is always noumber one in a book report. In the Ahnentafel(Ancestry) book the father of an individual has a number just twice that of the individual, the mother has the next number. These numbers are not the RIN/MRIN numbers used in the database. In the Modified Register book, the base individual has the number one, the rest of the individuals are numbered consecutively as they show up. Still not the RIN/MRIN numbers.
You could get rid of the numbers that do show up in the index, if you wanted to, by saving to a file and editing with your wordporcessor.
