dharris,

Perhaps the Help menu will help you:

Generation Numbering — You can choose one of two different methods for numbering the generations in your Genealogy report. Select Automatically find the oldest ancestor if you want Family Tree Maker to begin the generation numbering from the oldest male ancestor in the same blood line as the primary individual you have chosen for your report. For example, if you select yourself as the primary individual for the report, and your Family File contains information going back to your father, but no further, then your father would be assigned generation number 1 and you would be assigned number 2. Since you're the primary individual, your Genealogy report would begin the generation numbering with the number 2, next to your name. Select Assume the primary individual is the immigrant ancestor if you would like the numbering on your report to start with "1" regardless of how many generations precede the primary individual. The previous generations (older than the primary individual) will be "numbered" A, B, C, D, etc. This is the style of numbering traditionally used for ancestors who did not immigrate to the United States.

I think the key is the Generation Number is the Key, not the individual names.
