I have given my 3 children their own Copies of the Familyhistorian programme, which I use. 
As I add more information I send them (UK,US and NZ) a GED file.Plus scanned  Copies of old photos and documents.
 When we downsized, we shared out various"goodies" such as a Sampler , a Gran's wedding invitation etc. A large (very) framed wedding photo (ours).To my embarrassment ,openly displayed because my daughter loves it!!
Our son has the family Long case clock from my Husband's  G/grandfather.
OK that is fine as far as it goes, but if I want to leave a record to a FHS, and basically ones  main branches come from 4 (or more) different counties, then to one or to all.?
