From this I was able to find one of Ellen's younger sisters, Bridget, had married a Thomas Hickey in 1890, and three of their possible children but haven't looked too far into that line.
I have a list of probable Kennedy children of Archibald and (Mary) Jane's from the BDM index.
You can see from other posts in this topic that Jane's father was James FARRELL from their Marriage cert and we believe her mother was Bridget Tye/Tighe (and various other spellings) which would lend support to Sylvester Tye and Bridget being two of Jane's children. Also that Jane divorces Archie and remarries William J Davis.
We now know that Jane DAVIS takes care of her granddaughter Olive WADE from about 1903-5 (from Neale's link
