Irish Passengers Into Liverpool 1840's

If you use Ancestry or Find My Past, those sites have indexes to Catholic Registers Ireland.
The marriage I posted was from Castlemore  and Kilcolman Parish (Ballaghaderreen). You can just search the registers but it is more difficult.

It is on the border of Mayo/Roscommon.

There is this marriage but it is not that positive - bottom of right hand page

Thomas Brennan and Elizabeth Linnen January 1837

That's an outside possibility imo. I don't see Linnen becoming Lyons. More likely Lennon or Linehan.
Some Irish FH websites show surname variations.
There's also one on which you can do a search for parishes where a pair of surnames occurred.

I do what Heywood suggests reply #9, using free search, then look up possibles in registers on National Library of Ireland site.

Thank you! I will certainly take your advice although haven't had much luck on Ancestry yet. I have PM'd you too.

Thank you I will do as suggested. I agree with your comment on the Linnen, Lyons etc.

Can I ask the name of the site that has pairs of surnames?

It's also useful for registration districts, finding parishes and looking up names of places and other stuff.

I wasn’t too sure re the name, as I said, but the writing isn't that good to be fair 
The difficulty is that the records you seek are Parish records and not all those have survived and you need the County and Parish 

The name Brannon could also possibly be Brennan/Brannen etc depending on interpretation of the person recording it.
Local Church records may be useful with Godparents names etc who might be relatives or friends from the same area at home.
There are quite a few Brannon variations in Runcorn you might want to look at too to see if there are any connections.
Which of Thomas and Elizabeth’s children is your ancestor?
