Hi, yes that was a typo. It is indeed Sullivan that I meant to type.
I have read somewhere on here in someone's tree (which I cannot find now) that these people were both foundlings and that they married in Mullingar.
Now, if they were foundlings, it is unlikely there is any further history on their ancestry, and I assume their surnames were of the families they were adopted by??
There is also the very real possibility they were children of Irish travellers, given that Mullingar and Athlone are both places which were densely populated by travellers.
If they were foundlings, it is also feasible they were reared in workhouses?
I speculate a lot here as this is all I have at my disposal.
