Michael and Bridget Gilmore Manning

I'm looking for help to get great, great grandpa Michael Manning and his wife, Bridget Gilmore Manning on the boat from Ireland.

I have seen some boat manifests that indicate they were already married when theycame to the U.S. around 1851, though I have learned Manning is a more common name than I thought.

Michael was born about 1829 and Bridget in 1831.

I do not have any information about their parents.

Thanks for any help.
