Goggin/Cronin in County Cork

I’m looking for information regarding my ancestors who immigrated from Ireland in the early 1850’s and their ancestors.  My 2nd great-grandfather was:

Patrick Goggin

BIRTH ABT. 1800 • County Cork, Ireland

DEATH 1857 • Old Town, Penobscot, Maine, US

My 2nd great-grandmother, Patrick’s wife was:

Johannah Cronin

BIRTH ABT. 1805 • County Kerry, Ireland

DEATH 31 DEC 1891 • Orono, Penobscot, Maine, USA

All census information list varying information regarding dates of immigration and ages of all these people.  Patrick and Johannah’s children were all born in Ireland before immigrating to the United States. Their names were:

David Goggin

BIRTH: 4 MAY 1845 • County Cork, Ireland

DEATH: 8 MAY 1926 • Orono, Penobscot, Maine, USA

Johannah A Goggin

BIRTH BEF. 27 MAR 1846 • County Cork, Ireland

DEATH 29 OCT 1922 • Orono, Penobscot County, Maine, USA

John Joseph Goggin

BIRTH 7 MAY 1848 • Clountead, Ballingarry and Ballymartle, Cork, Ireland

DEATH 1 JUN 1927 • Orono, Penobscot, Maine, USA

Patrick Charles Goggin

BIRTH 5 JUN 1851 • County Cork, Ireland

DEATH 17 MAY 1928 • Orono, Penobscot, Maine, USA

 

These people may have entered Canada before coming to the United States, but this is pure speculation on my part. John Joseph Goggin married someone from Chatham, New Brunswick, Canada. Chatham, New Brunswick and Orono, Maine are more than 300 miles apart.

Any information regarding the Goggin and/or the Cronin families in County Cork and County Kerry would be deeply appreciated.  I’ve been searching for more than 20 years.
