Mom and Dad (Chin Wee and Yim Wong) married May 24, 1936 (revised 4/9/2020, Mom was born Dec 1918, Dad's dob: Feb 1919). 
Here's a photo of them with Chin's parents, King and Suzon Mar, along with King's mother, Cheung Tsui Tai.  Back in the old country in Baksha, China.  We are Toisanese, i.e. Southerners.  Not Mandarin Chinese speakers. The photo may have been taken Dec 1937; King was pretty good at recording photo dates.

Here's how my Dad and Granddad looked in 1942, right after Dad enlisted in the US Army after Pearl Harbor.
