A search of the Illinois State Marriage Index indicated Asa Landon married Mrs. Mary Sargent in Winnebago County, Illinois in 1849.
This copy of the marriage license was obtained from the Illinois Regional Archives Depository at Northern Illinois University in DeKalb, Illinois.
The date agreed with the entry in the index. This was not a copy from book I, as referenced in the index, as that is the marriage register entry and this is the actual license.
Hiram Lake was a neighbor of Asa Landon. Lake purchased property in the same section as Asa Landon.
I'm still trying to connect Mary Sargent's son Ira, with my Ira who first appeared in the 1880 census in Hancock County, Illinois.
