Hello Collen, My name is Peter Callaghan and My Wife is a Mary Fitzpatrick and I noticed a Magret Fitzpatrick mentioned on your Enquirey. I did a little checking and was able to verify that Morris Baptism was 10th June 1821. But It only mentioned the Mothers married name not maiden name.

I couldn't Find any information on Patrick Delaney or Margaret Fitzpatrick. If you have anymore information on Morris's Father and Mother that would be a big Help. The information proves his Father was a Patrick Delaney and that the Mothers first name is Margaret but was her maiden name Fitzpatrick? I hope this information helps you in your Search.
All the Best
