Looking for info on the Weitzel family from Fulda, Hesse, Germany

I am interested in finding information about the Philip Weitzel family.  Philip was born in 1804,  His wife Margaretha was born about 1800.  Their children John (b. 02 Feb 1837), Theresia (b. 15 Oct 1838), and Lucia (b. 06 Dec 1842) were from Fulda, Hesse, Germany.  They settled in Mercer County, Ohio in 1848.

Any help would be appreciated.
