You could look through shipping records, try Ellis Is. NY
as they have passengers going in both directions to and from Ireland.
1869 are Civil Records and copies of anything after 1864 can be obtained from the General Registry Office, Dublinwww.groireland.ie
Kerry does not belong to an organization/foundation of irish genealogy offices, so luckily the records you are looking for are after 1864.
I think there maybe two different Daniel Horgan's one with a wife Bridget Connor and and the other Bridget Cahil.www.familysearch.org
has civil records from Kerry
Bridget Horgan born 24 Oct. 1869 #621 Castleisland, Kerry
#101199 Daniel Horgan/Bridget Connor
Honora Horgan born 14 May 1868 #824 Castleisland
Daniel Hogan/Bridget Cahill #101169
the same record are on a CD I have from the LDS. The only possibility is that the person who did the transcribing copied the wrong wife's surname.
I didn't understand Thaddeus and Daniel Horgan know as Timothy. Is Timothy a surname? or a place
Many Kate and Mary's and father Daniel - wrong wife.www.censusfinder.com
