Notable orphans and foundlings include world leaders and entertainers
I never knew that.  Please acquaint me with this phenomenon.
An orphan is someone whose parents are dead, unknown, or have abandoned him or her.
How do they go from being an orphan to being a world leader/  Seems like quite a climb from their starting position.
The orphan train movement transported orphans to larger cities and foster homes.
I have not heard of the orphan train.  Is this a real train that they ride on or some sort of literary invention?
A real train! They operated from 1854 and 1929
Let me get this straight.  A person starts as an orphan, gets on a train, and when they get off they are a world leader?  I think you have been watching too many movies.
