This is a relation of mine. My grandfather was Raymond Spiecker. His parents were Julius and Agnes (Kuntne)Spiecker.
Raymond's brother was Ernest (he changed his name to Frank).
My mother believes you were at a funeral with her when she was a teenager and said she almost fell over when you walked in because you were the spitting image of her grandmother, Agnes.
I don't know much about Mary aside for the fact that she was a lovely person. She would bring hot cross buns to my Grandparents house on Good Friday.
