Do you think Fern could have been Lulu's daughter since she was born before Harvey married Lulu? Have you ever found a death record for Lulu? I have seen where people say they are widowed in census records and they weren't. Have you traced Guy to see if Harvey is in his vicinity? They seem to find each other. I found Guy living in the home of Mach and James Harris in Sweetwater county, Wyoming in the 1900 census. Guy is a boarder. On HeritageQuest, the indexer misread his place of birth and put Texas. On ancestry.com, you can read the census record more clearly and you can see that it is Kansas.
