I'm doing a little research for my third cousin, in the U.S. She is related to me through her father's father - but her father's mother was Ellen Sophia Tångring (b. 1875 in Ekeby, Östergötland), the daughter of Carl August Tångring (b. 1850 in Ekeby) and Johanna Sophia Isaksdotter (b. 1851). Carl August was the son of Carl Peter Tångring (b. 1820 in Hällefors, Östergötland) and Eva Charlotta Henriksdotter (b. 1821 in Tjärstad, Östergötland).

So, Carl August and Augusta Lovisa (Swedish version) were siblings. There were indeed nine siblings:
Oscar Fredrik, b. 1845 - two months after his parents wed
Augusta Lovisa, b. 1847
Carl August, b. 1850
Maria Charlotta, b. 1853
Vilhelmina, b. 1856
Emma Carolina, b. 1858 d. 1859
Emma Mathilda, b. 1859
Ida Amalia, b. 1861
Claes Henrik, b. 1867 d. 1868

Carl August with wife Johanna Sophia Isaksdotter (b. 1851) and their three children - Ellen Sophia (b. 1875), Carl Gideon (b. 1877) and Torhilda Christina (b. 1880) - emigrate to America 12 May 1882.
At least Ellen Sophia eventually winds up in Chicago because that's where she lives after marrying my grandmother's cousin.

The Tångring family is an old smithing family.
