My mother was British (she went through the Blitz, etc.), and met my father during the war (he was a bomber pilot in the 8th Air Force based in England); they married after the war.
My mother always said that Churchill gave them (the Brits) hope, but that they (the Brits) finally believed in victory once the U.S. joined the fight. She said the Brits were stunned at the firepower “the Yanks” showed up with.
Alas, both my mother and father are gone now. I miss them still, and always will.
You and Winston Churchill have something in common...in your case, your Father was the American! I have always loved that about Churchill, that his mother was an American!
I know how you feel about your parents...mine have both been gone for over 15 years now. And I do miss them. A different generation, to be sure.
