I guess the only way I can even think to begin to research this is message REA and ask if they can ask the consignor for info. I am sure they will not divulge any personal info on the consignor directly. Then the next step I would imagine would be be the consignor to look into the property records or give me the address so I can. Then after that probably look up the family members of the house owner. They will probably have no info on a great relative like that, but who knows if they do they may have more of those cards laying around.
