My daughter's CD sure seems to be from my wife's side  (her sisters have
digestive problems). Interestingly, my wife's father has alzheimers.  Though
we don't know which side of my wife's family the CD came from, we have
suspected it was from her mother's side (mother's grandfather's family had
many infant deaths - some due to "digestive problems"), but note that my
wife's mother's mother had alzheimer's as well.
