George William Wilkinson - Please help! Agnes is showing married to her uncle

I disconnected Agnes from parents a she is not mentioned in the About and the relationship cannot be correct because surely she did not marry her uncle. Hopefully she did not have any sort of "relationship" with him.
If someone knows a secret, please share it.
I hate disconnecting but this seemed the obvious thing to do...
Will seek to add parents for her based on sources and DNA matches.
Thank you for any assistance
