Not as yet for me is there any marriage cert. or .. well all i have is confirmed of how my gr-grandmother arrived here in USA; 1881 she was 21 arriving in New York\ port: Grimsby via Liverpool.Dep. Date July,22,1881* Giansborough, Hawkins,Dampfschiff, my first hint is my mom's cousin' book she put together about the Sigfred & A. Henrietta Rohde' family. the first son married this Johanna Von Trapp before 1884, the year my grandfathers oldest sister was born Lydia Matilda Rohde. so I started my family tree with this info I have more; but not yet have info of who her family were or parents names a brother/sibling who was 17 (Paul Trapp , surname is given in Ancestry.com site) He had a one yr old son, Fietz. so too i'm slow to access the naturalization papers for her & family. $amount lacks. but i'm sure the papers are there. thanks for replying all the dates come together , yet this does not mean this is 'my'Johanna. my next proof will be if she is of the singing family or if that was passed around. anyONE finding a newsarticle stating that so an so visited the dakota cemetary in Wisc. USA where (abt 1945-65)the Johanna Trapp Rohde is identified with headstone there. she was married to herman C. A. Rohde and passed on Aug.15, 1891, before her little baby was six months old. five children: Lydia, Oscar, Louis, Edmund, & Jesse Rohde
