I thought an obituary might help find Elizabeth/Bridget, but Thomas Woods' obituary only confuses things. It says he was survived by six sisters but only mentions five, including two named Mary. It doesn't mention Elizabeth/Bridget or Margaret. If you can account for Margaret, then maybe the extra Mary in Thomas' obit is really Elizabeth/Bridget.

Here are the other dates of death I found for the other children. I could see obituaries for most of these, and they only mentioned a spouse or a child.
Maybe someone can find a more informative obituary.
