I think it might be a misspelling/transcription error of the name 'Mordecai'. Who might be this man, son of James and Lina (Toomey/Toumey) Hudson. There are more censuses etc. on Mordecai, James, Lina on familysearch.The Mannie N in the other census noted is female which would not match to Nadecai listed as male.
