McCarthy/Cronin family search

Searching for information/descendents of Charles McCarthy and Ellen Shea. Known children are: Daniel b. abt 1810, Charles b. 20 May 1820, Denis b. abt 1823 and Catherine b. abt 1834.

Daniel married Johanna Cronin in Ireland. I have what I believe to be the record from West Schull for the baptism of their daughter Mary in Feb. 1846. She was b. 9 Oct 1845. Johanna's father was Daniel Cronin

Charles married Catherine Sullivan in the US around 1851 but she was from Balleydehob.

Denis married Margaret Tobin in the US. She was from Whiddy Island.

Catherine married Michael Garvey. It is assumed they married in the US. I don't have much more info about her.

Any info or help is appreciated.
