Let's hope she never makes the connection and, if she does, I hope for your sake she has the sense to keep quiet. I have had a terrible experience myself when the two worlds collide. Cannot go into details but my case has caused me a lot of distress, embarrassment, loss of sleep and emotional heartbreak. In your case, even if the woman tells her brother you were at the office would she really remember the details of your case to repeat them now? I'm sure she knows about the importance of confidentiality.
