Not only was he listed, but he is identified as 'father-in-law'. How did I miss that? Was he living with Aunt Myrtle? Since I already had my grandparent's record for the 1940 census, he couldn't be living with them. Or, could he?
When I checked the page, he was the top entry on the page and there was a note that it was continued from the previous page.
Guess who I found on the previous page? My grandparents and family.
