Once Upon a Time was a show that did this very well. Even Regina's character was played well by Ava Acres and her mother had a very excellent younger cast member also. I watched more for Mr. Gold/Rumple than anyone. Robert Carlyle is amazing.
Emma in Once Upon a Time (played by Abby Ross as a teenager and Jennifer Morrison as an adult)
Fun fact: McKenna Ross (who played young Sabrina above and a number of other young versions of characters on this list) played the kid version of Emma.
