I had just returned from a two-week vacation to Hawaii on April 1. I was so jet-lagged that I completely forgot about the 1940 census release until I went to work on April 2. This was probably for the best.
I first looked for my relatives that had lived, and still lived in the same place in Mount Olive, Wayne County, North Carolina. It was just a matter of looking through a few images (OK, about 40) to find my grandparents, and their daughter, my mother. The rest of the family was nearby.
Then, I looked for my other grandparents in Fayetteville, NC. I even had their address. But their part of the street was not in the enumeration district (ED) that was indicated through Stephen Morse's website. Not his fault. I looked at the map of enumeration districts - the area where my grandparents address would be was annexed into the city in about 1947, but was still in the county in 1940. This was at a time when Fort Bragg was increasing in size considerably. After looking through parts of two enumeration districts, I found the correct address on the first page of ED 26-39B of Cumberland County, as if there was some confusion about what district this street belonged in. My great-grandparents were living next door. No street name or number was recorded.
