The Aunt We Never Knew

At Dad's funeral, his brother dropped the bombshell that they'd had two other siblings who died shortly after birth (as in, Grandma came home from the hospital without them). Today I received this, which he sent me.



So my Aunt's name was Margaret. No middle name, just Margaret Jones.

I shall try to find out more about her, not that there's much to find out, as apparently she only lived a couple of days. Still, I'd like to know whatever there is to know. When did she die, and of what? And where is she buried? I'd like to put a flower on her grave, if she has one.

Now if I can also discover the identity of the other sibling...

UPDATE: My mother says Grandma had two stillborn children, of which Margaret was one, and she came to believe, later in life when these things became known, that it was due to the Rh factor. Her blood type was negative.
