On 9.6.1852 a group of 458 persons out of Viernheim/Hessen emigrated to New York. Viernheim is a small village near the airport Frankfurt/Main. In this group there was Mathias Wunder and his wife Eva, born Kempf. They married in Viernheim on 16.5.1850. In the next 50 years a lot of Viernheim poeple followed there relatives to USA. I found in the parish register of Viernheim some persons with the family name Wunder, but no Alexander Constantine. I found 3 Alexander Wunder but they did not emigrate. Have you some more information?
