I'm sorry, but I can't say if Nina Ritter is a relative of our family.
The five Ritter-brothers and sisters emigrated from Liechtenstein. Liechtenstein is a very small country between Switzerland and Austria. In this time Liechtenstein was unknown in the USA. Therfore they often declare Austria or Germany as native country, which were more well known..
THE RITTER-BROTHERS AND SISTERS
MAGDALENA MEIER NEE RITTER (1847-1924) emigrated in 1883 to Fourmiles (today Melbourne in the State Kentucky). Later she moved to a suburb of Cincinnati OH called Elmwood Place. Magdalena married Joseph Meier. They haven't got any descendants.
ANDREW RITTER (1848-1913) left his homeland in 1868 and emigrated as the first of the Ritter family to America as a stone-cutter and farmer. In the middle of the seventies he married the German Mary Petronilla Schnabell, who was born in Kentucky. Joseph, the first of ten children, was born in February 1876.
THERESIA WANGER NEE RITTER (1861-1936) married Kaspar Wanger. The husband Kaspar Wanger emigrated to Elmwood Place, Ohio in the year 1891. There he could work for his brother-in-law Ferdinand Ritter, who had developed in the meantime a flowering cement and brick business. One year later Theresia and the children Edith and Andreas could follow her husband and father Kasper to America. The third child and the further children were born in America.
