Barbara Pierce Bush was just 16 years old when she met future husband George H.W. Bush, beginning an epic romance that would last more than 76 years until her death at 92 on Tuesday.

After a year and a half of dating, George proposed in August 1943 — right before he was deployed to serve in World War II as a Navy pilot, Brides.com reported. George named three of his Navy planes after his sweetheart, including a torpedo bomber called “Barbara.”

Poppy and Bar, their nicknames for each other, bridged the gap between them by writing overseas love letters.

In one letter dated Dec. 12, 1943, George wrote to his “darling Bar” about how happy he was to read their engagement announcement in the newspaper.

“I love you, precious, with all my heart and to know that you love me means my life. How often I have thought about the immeasurable joy that will…
