Michael Galvin/Galivan and Mary Connell Co. Kerry mid-1800's

Hi – I am looking for information on Michael Galvin [or Galivan] and Mary Connell from Co. Kerry. Not sure if they immigrated to the US. They had a son Michael and possibly a daughter Honora. Michael Jr was born in Ireland in the vicinity of 1855,immigrated to the US in the 1870 - 1885 timeframe and lived in Cincinnati Ohio where he married Mary Burns and ultimately settled in Chicago [West Town, Sholto St]. They had many children, including James, Bessie, John, William, Helen, Lauretta and Nora/Norine. If Michael Jr immigrated with his parents, they may have started in Washington D.C.

Honora Galvin/Galivan, who I think is Michael Jr’s sister but could be his aunt or a cousin, was born in Kerry around 1845. She married Jeremiah O’Brien around 1868 probably in Washington D.C. and ultimately settled in Chicago on Blue Island Ave where they raised 6 kids -- John (born in Wash DC), James, Margaret, Elizabeth, Anna and Robert.

Thanks for any information, especially townland for Michael Galvin/Gallivan and Mary Connell and relation between Michael Jr and Honora.
