1. Import each GED file into its respective, new, empty RM database.
2. From the One_Family database file, drag either the Father or the Mother
and drop them onto an open area on the OnePersonTarget database with the 
option Descendants only.
3. See what has happened to the source family and the unrelated person in
the target.

This is a microcosm of what can happen with a large transfer to a large database.
