Hi Elizabeth,

I use FTM 7.5 and find that it is possible but slightly cumbersome to export groups of individuals - you do it by developing a tree (from the descendant/ancestor etc tree options) of the subset of people you want and then selecting option File/Copy export Individuals ... from the topleft menu option. One is then prompted for a file name and location which you give and also select "Gedcom" from the option "select file type".

Good luck - John
