George,
I found Carmen on the Social Security death index, is this the right one?

problem is my newspapers don't include those years, and I couldn't find Catherine or Susie in the listings. I had hoped that finding a death date may help locate an obituary.

Have you used the family search pages? If not, read about it here,

https://familysearch.org/about

then search here:

you could probably recognize something I couldn't.

Here is the link for social security, maybe you could have better luck with Carmen and her mother to find their exact death date.

I will still try for the obits, if I find them, I will certainly send them to you.
