Thanks to all who offered help in locating my Dewees family in the 1920 census. The responses confirmed my suspicion that the family was probably missed by the census enumerator in PA, NJ, DE, or wherever else they were living in 1920. I try to keep track of relatives I cannot locate in a particular census. The most problematic census for my relatives has been 1910, with twice as many missing as in 1920 and a third more than in 1910 and in 1930. From time to time, I conduct another search for the missing relatives, sometimes using a different website (e.g., FamilySearch or HeritageQuest instead of Ancestry.com, on which I do most of my census searches). I estimate that I find my MIAs about 35 percent of the time. Mark Lomax California
