I do have alot of Eiserloh research that was done by my Uncle. His research goes back to Nicholas John Eiserloh, Sr., who was born in 1835 in Prussia Lautzenhausen Kallang Germany. Nicholas married Maria Henriette Eckard (born 1833 in Prussia Varel Oldonburg, Germany). Most of the Eiserloh's are related or so I am told. I do not know if Nicholas has any siblings. I can tell you the name of his children Elizabeth Charlotte Eiserloh born1861(married Wendel Roeling), Nicholas John Eiserloh born 1864(married Pauline G. Neiderer), Bernard Martin Eiserloh born1868(married Dora Keese), Marie Eiserloh born 1870(married Henry Moonen), anton Henry Eiserloh born 1874(married Anotinette Henrietta Sprea).
