Searching for information on the Walden family of McLean/DeWitt Counties. Martha Jane born 1822 and died about 1847,48.

Martha Jane Walden married 22 September 1842 in Clinton, DeWitt, IL to George Perry Brittin had son Morris Elijah born 11 March 1844. They only had one child, Morris Elijah and she died around 1847-1851. George Perry married Rebecca Walker Jan 1852 in DeWitt County and had several children. Need information on burial of Martha Jane Walden Brittin. Can not find his burial info either. It is said his farm was on the line between McLean and DeWitt County. I found info about George Perry's second wife's death in a Clinton paper in 1874. Any help out there? Do not have exact death date of George Perry Brittin either. Just know when he disappeared off census records. He lived on his farm many years after his wife died and then on census with his daughter in 1900. Is there any newspaper clippings?

There are many Walden families in McLean/DeWitt area, including William and Jane Starr Walden (1806-1872 and 1805-1889) who named one child Elijah and one son Morris. They are on 1850 census in DeWitt County. Wonder if this is any relation? There is also an Elijah on census born 1700's.

Any help appreciated.
