I saw this request at the Alameda County message board Ancestry.com:
"Seeking information about descendents of sisters
Ellen Kennedy who married William J McNally; lived in Oakland and died in Alameda Co California in 1955.
Winifred Kennedy who married Patrick Conniff; lived in Oakland and died in Alameda Co California in 1946.
Their parents were Patrick and Bridget Kennedy of Old Castle, Co Galway Ireland."
I found the obituaries for both Mrs. Ellen McNally and Mrs. Winifred Kennedy. I hope that they help you with your research.
