The one thing I'm pretty sure of is that Heinrich the son (born in 1858) has become Henry Ruper in the 1880 census. He's 22 years old, single and working as a farm laborer. He's living in the town of Otto in Cattaraugus County in Upstate New York. He's living with the Miller family, also from Mecklenburg. I assume their name was something like Muller before it got changed, too. It's probably the Miller farm where Henry Ruper works.
