Although Thomas was your grandfather, I believe that your great-grandfather had a brother Thomas also because at the bottom of the document I have, written very small, it says that Thomas had passed away when the family immigrated in 1866.So, possibly Thomas was your grandfather and another Thomas was your great great uncle.
I know only that they came to the U.S. in 1866 as a family. I have just started with this part of my family, after going back ten generations with the Myers'/Boyers.I live near the Pennsylvania state library, and there are ship records there.We will go over there ASAP and see if we find anything.
I only know of her parents, Joseph and Charlotte, and you already know about them. The only information that I have I already gave you, but as I find more I'll be sure to send it to you.
