I'm not positive about this being your guy, but in trying (not very successfully) to find Micagei in 1850, I found the following family unit in West Cocalico, Lancaster, Pennsylvania:
Edd Pears [a possible spelling variation for Pierce], 59, laborer
Elizabeth, 56
John, 22
Also living in the same household is: Joseph Lauckenbread? [difficult to read], 45, laborer; Samuel Dulinbean?, 23, laborer; George Frantz, 30, laborer
