Located the 1940 census record of the Arthur D. Weaver household in Lake County, Indiana. Arthur's wife, Olive, was my maternal 2nd cousin 5 times removed. Our common ancestors were Alexander Crockett and Elizabeth Watkins. Olive's parents were William Perry Crockett and Sarah E. McCauley. Arthur's parents were Oran Weaver and Mahala Frame.
At the time of the enumeration, Arthur and his wife were living in Ward 3 of the city of Hobart. The census states that Arthur owned his home and that the value was $5000 and it was not a farm. Arthur was 76 years old and was born in New York. His wife, Olive, was 67 years old and was born in Illinois. In 1935, their residence was the same place.
According to my database, they were the parents of 7 children : Frederick, Lola, Jesse, Bessie, Edna, William and Coletta. None of them were living in the household in the 1940 census.
The record shows that Arthur and Olive had both completed the 8th grade in education. Neither of them had an occupation listed in the census.
If you have any additional information or are related to this family, I'd love to hear from you.
