I have a Michael Schuler/Schuller married to a Elizabeth Luy.
I found a Michael Schuller in Bloom Township of Cook County, Illinois in the 1870 Census.
Schuller, Michael, 33, W, M, Farmer, France Schuller, Mary, 24, F, W, Keeping House, Illinois (maybe Mary Elizabeth?) Schuller, Michael, 3, W, M, Illinois
I found an Eliza Luy in the Illinois Census Index for 1860 living in Bloom Township, Cook County, Illinois.I will have to check her out the next time I go to the library.Looks like Eliza Luy was single and living there in 1860. Maybe they got married in 1866 or 1867 because their son Michael is 3 in 1870.Then, Michael Schuller is listed as head of household in 1870.Michael is 33 and born in 1836 or 1837.
