Does anyone know what the abbreviation “OT” next to a name in the 1910 US census signifies? See, for example, the entry for Harriett HARRIS in the cropped attachment Harris.jpg. I am guessing that it means “Out of Town,” because that would explain why she is also listed with her husband and oldest child as Hattie SCHULTE in the second attachment, but it is only a guess. Both censuses show her as married four years with one living child, although her listed ages differ by one year.

I also do not know who the granddaughter Bertha MARKS in the first attachment was. Based solely on that family, she would appear to be Harriett’s daughter, but that cannot be correct. Also note that Harriett’s mother Fannie (Frances) nee LAUCHHEIMER had one child no longer living who could have been Bertha’s mother if that person had not died young because she is also not mentioned in 1900.

There appears to be no official meaning to the notes/abbreviations you see.

It appears that it is a notation for who spoke to the census taker and stands for "other". That is to say, not the heard of the family or the spouse. Most of them read "Wf" for wife.
