I'm looking for information on Nelson Foster (1820-1889).  Originally from Ohio, 4 children by first wife (unknown), moved to Fulton County early 1850's.  Youngest daughter (Mary A) by first wife, was born about 1852 in Illinois.  Then he married Louisa St Clair April 1854 in Fulton Cnty, they had several children. 

Nelson moved to McDonough county before his death and is assumed to have died there, however I have not been able to find his gravesite in either county as of yet.

I am descended from his first marriage, but would like to find out anything I can about the family.
