I am running an even earlier version of FTM. I think version 6.0, but I like it and don't really want to update.
The only suggestion that I can make is to make a copy of your present file and then go into that copy and remove the persons to bring it back to a family or group of families.
There probably are better ways, but that is what first that occurs to me.
An electronic copy of the Ault Genealogy would be a great benefit to people.
There is the issue of the Female family members who were sort of dropped by Garnett Ault.My wife is descended from Micheal Ault's grand-daughter Maria (1824-1912) however, once she was born Garnett included almost no info on her and her descendants are completely abandoned.Don't get me wrong, his book is a real asset, but an electronic copy would make it a living document.
I think it would be interesting for someone to have an ititial electronic copy of Garnett's book and then update the data.
