Any KERRIGAN or MORAN Researchers here?

Looking for Roger and Catherine (Nee MORAN) KERRIGAN who emigrated from Sligo sometime between 1836and 1842.
I ran across a Missing Persons entry that mentions aTimothy and Bridget KERRIGAN, "natives of Ballisodare"(parents named Darby and Sabina KERRIGAN)who came to America in 1839 and 1854 respectively.

I am thinking (hoping!) that perhaps Timothy was a sibling of my Roger.

Do any of these names sound familiar at all?

Thank you.
