Angela Shan

 or just Mrs. Shan in the movie is Darren and Annie Shan's mother and the husband of Dermot Shan. She had a stamp collection before Darren's 'death' but it is unknown what happened to it now. She was obviously really upset when Darren 'died'.

She later moved out of the house with Dermot when Annie was old enough to live on her own but had helped Annie raise Darius Shan, her grandson before then.
