I've identified the eleven ancestors that I want to look up on Tuesday.
2. Joseph A. Huigens, Jr
3. Shirley A, Ogden
4. Joseph A. Huigens
5. Julia Huigens
6. Emery J. Ogden
7. Esther L. Ogden
8. John Huigens
9. Mary Huigens
12. William F. Ogden
14. Gustaf A. Johnson
15. Rose Johnson
That's a lot of people. More than I thought I'd find. My dad's other grandparents died in the early 1930's. My mom's grandmother died in 1938.
Fortunately I can reduce this to five households.
1. Joseph A., Julia and Joseph A. Huigens
2. Emery J., Esther L. and Shirley A. Ogden
3. John and Mary Huigens
4. William F. Ogden
5. Gustaf A. and Rose Johnson
Next comes determining where they lived in 1940 and then the Enumeration District (ED). For four of these households, this is a piece of cake. They lived in the same place they did in 1930. So all I have to do is find the ED for 1930 and use Stephen Morse and Joel Weintraub's 1940 ED Finder to convert them. Here's the results.
1. Joe and Julia Huigens family in Sheridan CO., NE 1930: 81-27 1940: 81-7, 81-12, 81-18, 81-26
2. Emery and Esther Ogden family near Pine Ridge, Shannon Co., SD
3. John and Mary Huigens in Creighton, NE 1930: 54-6 1940: 54-6
4. William Ogden in Mission, SD 1930: 61-40 1940: 61-1, 61-26
5. Gust and Rose Johnson in Henning, MN 1930: 56-45 1940: 56-46
So that's a little more complicated than I thought. Only two are a direct one-for-one. Still it won't be too bad. These are rural, sparsely populated areas, so I won't have too many pages to look through. By reading the ED descriptions, I can make some educated guesses which EDs to start with.
According to my mom, her family was living on a dairy farm near Pine Ridge, SD when her sister Margie was born in Nov. 1940. That's not where they were in 1930, 1935 or 1945. There are only 8 EDs for Shannon Co., SD: 57-1 through 57-8. Again, these are areas with low populations so it won't take long to scan through them.
It looks like I'm all set for Tues. The harder part will be trying to find various generations of aunts, uncles and cousins. That's a whole other ballgame.
