I added census records from ancestry.com for Allen West in Nebraska and Wyoming and his father William West in Iowa. Taking a snapshot of Allen and Mary Alice West's neighbors in 1900 is an interesting study in extended family. Allen and Alice's daughter Della married Louis Patch, the son of their neighbor, Charles and Eliza Patch. (Her first of two marriages.)
Allen and Alice's grandson Hugh Russell married Florance Predmore, granddaughter of their neighbors, Nelson and Fannie Predmore, daughter of Rufus. (His first of two marriages.)

The stumper of the night is George Harry Worth. I've looked for this several times with a variety of spellings in the 1930 census. He should be in Loup County, Nebraska, right where he was in 1900, 1910, and 1920. He died in 1934 at the home of his daughter Elizabeth Jones in Loup County, but he is not enumerated with Frank and Elizabeth Jones. Where is George Worth in 1930?!?
