Im not related to your tree but have been looking into it for you as I have been researching Milverton for my tree.
The only Edward Richards I can find on 1841 census married to Ann states he was born in 1811. I have checked the Milverton parish records but cannot find his birth, only his marriage to Ann Hancock on 10.10.1831.
Also on the 1841 census are a couple of other Richards families which could well be siblings as they often stayed in the same area.
There is a John Richards aged 50 and wife Sarah
Also a James aged 45 with his family and a father John aged 80, so this could well be the father of all three of them. A John Richards died in 1846, which could be the father.You could possibly send for the death certificate which may show details of a late wife or who reported the death which may tie up with your family
Good Luck
A
