kathyb1955 on Family Tree Circles

I am searching for any information about my great, great-grandfather, Patrick RUSSELL from Ireland (Cork or Limerick?), married Bridget O'CONNOR (O'CONOR?) in the United States, possibly Illinois. They had, at least, one child, my great-grandfather, Robert Patrick RUSSELL, born May 1868, died October 1950, married Mary Ellen BARRETT (probably in Chicago, Il.) born 1871, died 1915.

Bridget O'CONNOR was born in Ireland and probably came from the same area as Patrick. Patrick RUSSELL may have had a brother, Robert. That may, also, have been his father's name. They, also, may have had a daughter (older then Robert) named Mary or Molly.

Any help would be very much appreciated. :)
