Why Sql Error Trying to Post

Why do I get an error when trying to post: My line dead-ends at George Myers (1823-1903) who m. Catherine Andereck (1829-1873). lived Marion Co., IL, and had issue Martha Ann, Isaac, William L, Andrew J, George W, and Eliza Jane (my gr-grandmother). I know much of their descendants, much of Catherine Andereck's ancestry, but nothing about Myers above George.
