Census information in 1870 was gathered by interview. The spelling of names in the census was often determined by how the respondent pronounced the name. Surname spellings were not really standardized until about 1860 and there may have been some period of adjustment before it was finally accomplished. In this case, I believe that all these names are the same in spite of the differences in spelling and pronunciation. This is a common situation in these censuses. Another source of spelling errors is in the making of copies of the census. The 1850 – 1870 censuses were copied twice, One for the State and a second one by the State for the Federal Census office. Our microfilms are of the second copy. The originals have been lost or destroyed over time. I am providing the information for the three census references you mentioned.

Please look up for me:
Mary A. Rodhouse MS 139
Also I found an Albert Rodehouse (P11) and a Henry Rodehouse (M6) and wonder if these are a mispelling (or a transcription error) of Rodhouse. I would appreciate information on these also if that would be possible.
Thank you very much.
