A very different type of question for you, I'm sure... Let me give some facts 1st... My grandparents had 3 daughters in the 1960's that all passed away, 1 was stillborn, another only lived a few hours after birth, & the other only lived to be 21 months. All similar causes of death; 1. Encephalitis complicated by post-op hydrocephalus/pneumonia terminal. 2. Encephalic. 3. Hydrocephalic/Spina bifida congenital... They decided not to try anymore, & adopted my mother at birth. All my life ive been baffled by their untimely deaths. I want to know what are the possible causes of this happening, not once, but THREE times in all three daughters??? & Ive read that there's supposedly like a 4% chance of this recurring in another child, so how would all three have this happen? Thanks in advance for everyone's time & input!!!

Welcome AWinnell87. Someone will be along.

Possibly the only way to find out would be genetic testing of both parents.
Or something environmental if they lived in the same place during that timeframe.
