Hey Carol, I'm Tim from Pennsylvania. My Ancestor on the Engler Line is John George Engler. he is Buried in Bethlehem, Pa. I'm not sure if the Iowa line is related but could be if it goes through Pennsylvania then moved westward to Iowa. Best wishes, TIm
I work on a few lines in the Engler family . The two major one are head by Theodore Engler of Germany came here in 1852 with his family and settle in Dubuque , Iowa area.
The other line I have also been work on was here in Dubuque Ia, and Andreas Engler was the head of that line. He also came from Germany but really sure when.
Anyone wanting to share or talk about the Engler line feel free to contact me.
