James Butter and family in 1850 census

I found Calvin Butter with his parents and siblings in Michigan in the 1850 census. I found one other Calvin Butter born in Ohio, but he is 4 years too old and he is a cooper by profession. I couldn't find any Calvin Butlers or Calvin Bulters born in Ohio that were within 5 years of his age.

I'm pretty sure this is the right one because his age is correct, his birthplace is correct. Also, his father is a Miller. Like father, like son.

These Butters sure do bounce around a lot.

There are a lot of strange marks in the Birthplace column. I think its something like Do for Ditto (meaning same as the person above). It's by far the most common mark on the page and the only one that is hard to read. I'm assuming it means ditto.

Apparently, the family just recently moved from Ohio to Michigan. My guess is that Benjamin is James's brother.
