Hi! Thanks for your answer.
Possible names are Karl August Rienas, Born around 1797, his son Wilhelm Rienas, Born around 1825 or his son, Heinrich Rienass, Born around 1875.
The names may have been written Rienass, Rienaß or Rienas. Supposely a few Brothers of one of them (likey Wilhelm or Heinrich) have immigrated into the US.
Unfortunately thats about all the info, I have.
