My one surviving uncle, by marriage, on my father's side just celebrated his 100th birthday.
The photo below was from June 1946 when John married my Dad's youngest sister, Ada Reba, youngest of 9 children.
My paternal grandparents are on the left, Omar, age 61 and Ada, 60. I don't know the ages of Uncle John's parents, but they look older than my grandparents. Her dress may indicate she was Old Order Mennonite, but I don't know for sure.
My grandmother was dead before this couple celebrated 10 years of marriage. I remember my mother crying when she got the phone call that Grandma had died. It was a very long distance call from Lancaster, PA to Dumaguete, Philippine Islands in 1954. I was just 3 years old. I have no recollection of this grandmother as we left the US to travel overseas when I was going on 2.
I haven't seen my Uncle John since 2013 when my mother died. I send him a Christmas card every year and did send a 100th birthday card in January.
