Emma was born in Iowa https://familysearch.org/pal:/MM9.1.1/MDJP-SR4
As you can see in this search, there were apparently two different Jacob families in the 1870 Iowa census. I didn't see any reference to Jacob, father of the bride, Emma. Sorry, I can't find the Albert Lewis connection. https://familysearch.org/search/record/results#count=20&query=%2Bgivenname%3AEmma~%20%2Bsurname%3ARiniker~%20%2Bbirth_place%3Aiowa~%20%2Bbirth_year%3A1854-1857~
