Dear Deb
Welcome to Ireland Reaching Out!
I had a look on RootsIreland.ie but could not see a baptism or marriage record for Charlotte. RootsIreland does have a baptism for a Daniel on 1st Jan 1824 in St. Michael's Parish, Limerick. His father was Daniel and his mother Elizabeth McInerney. The sponsors were not named. This could be your Daniel but I cannot be 100% sure. It seems that this is the only child they had or at least the only child recorded. Do you know if there were siblings? I was hoping to find a marriage for Daniel and this Elizabeth but was unsuccessful. I fear that they may have been born/married in a parish and at a time that predates parish records.
I wonder if you could have a look on Slater's Commercial Directory of 1846 would it list Daniel as a Jeweller?

As an aside, if you look at rootsireland there are a few baptism listings for children (none for Charlotte) with the surname McSweeney and a father first name Patrick. It seems that there are 3 families in all but the sponsors names/mothers' names might mean something to you. Rootsireland is a subscription site but you can subscribe for a month and leave it at that. You can also see the original baptism records here: http://registers.nli.ie
Let me know what you think
