Hi,
I have a feeling I've replied to one of your Rooney postings before, but here goes again anyway!
If you look on the IGI familysearch.org site, you will see that there is (some of ) the family of James Rooney and ELizabeth Taylor:
James Rooney, born 1833, Cumberland England
Married Elizabeth Taylor in Oct.1853, CUmberland
Children:
Lotitia Rooney, born 1849, England
Sarah Jane Rooney,b. 1856, England
James Rooney,b.1854, Cumberland, England
John Rooney,b. 1864, Cumberland, England.
Rosanna Amanda is not mentioned in the list here. And there seem to be gaps of some years, so maybe there were other children too.
If the IGI is correct, (and you do have to be a bit cautious, mistakes are known to have been made), then the father, James Rooney, was born in Cumberland in 1833; no birthplace is given for his wife Elizabeth Taylor. And as you have seen Ireland mentioned in the census, this could mean that Elizabeth Taylor was Irish, and although married in Cumberland, they returned to her parish in Ireland perhaps where they possibly had a couple of their children, before returning to Cumberland again.
Clearly there is a discrepancy somewhere, either in the census returns you have seen, or in the IGI - either or both is possible!
But at least it gives you something to think about!
Good luck,
Mags
