I hope you are still interested. I am great-great granddaughter of Johann Frederic Vahle (1825-1880) who was born in Eickum, Westfalen, Prussia, immigrated on 19 Nov 1846 on the Meta from Bremen to New York, lived in St. Louis. His children were Anna (1849), Peter Henry (1851), John Friedrich (1854), Friedrich Wilhelm (1859)who is my great-grandfather, Anna Louise (1861), and perhaps Friedrich Wilhelm (born circa 1842 in Westfalen, Prussia and dying in Missouri on 27 Nov 1846).
I'm not positive about his wife but it might be Anna Catharine Ilsabein Meierahrend who was born 31 May 1821 in Oetinghausen, Westfalen, Prussia.
Please contact me as I have more and hope you have something I don't have.
