Once Siri remembers a relative, Siri can no longer find them in contacts.

Question

At first I was impressed with Siri, since it immediately knew who my Mother was.  But after I said yes to Siri's question, "Do you want me to remember Ms. so and so is your Mother?" All that was impressive went to annoyance.  Now, everytime I ask for Siri to call my Mother, I get told that Ms. so and so cannot be found in my contacts!  Yet it must be finding it, since it knows my Mother's name.  If I remove from my contact that Ms. so and so is my Mother, Siri works again.  But asks again, "Do you want me to remember Ms. so and so is your Mother?"  If I ever answer yes, Siri stops being able to find my Mother.  If I answer No, Siri works fine.
How can I get Siri to remember my Mother and to know which contact is hers?  Or, can I get Siri to stop asking me, "Do you want me to remember Ms. so and so is your Mother?"
I also noted that I had "Mother" under nickname in my Mother's contact.  I have removed and added it, doesn't seem to make a difference.  The only difference seems to be the related link in her contact.

Hi.
Thanks for the reply but that isn't the solution in this case.
This issue is due to prefixes and suffixes in the contact data. They seem to confuse Siri, so I hope a fix is on the way soon. In the meantime, the workaround is to delete all the Mr/Mrs/Miss/Dr or Snr/Jnr etc. references in your contact data.
Siri will now work fine... unless you have two contacts with the same name and were relying on the Snr/Jnr suffix to differentiate. In that case you need to assign at least one of them a nickname and use that when using Siri.
In my case, after deleting the prefixes and suffixes, I have the same name as my father. Although Siri correctly identifies the contact that is my father and gives him the "Dad" nickname, it puts his full name in the Father field on my contact record. Whenever I ask for details regarding my father, Siri recovers my data instead, this was fixed by editing the Father field in my contact to say "Dad" rather than his full name.
