Henry Christian Fredrickson married Anna Erickson in 1866. I have a certified Rock Island marriage certificate, however Henry C.'s last name is spelled "Fredrick" instead of "Fredricksom". I belive they are the same person, however because I know the name of his wife and the children were born in 1868 and 1873, and I know they were born in Rock Island. Does anyone have the 1870 census to see if they are there in Rock Island? Pam in Calif.
