Nugent Family

I have been searching for info on Nugents (Charles 1800?? to 1840??) in Ireland. I was originally told my gggrandfather, James,(1836 to 1926) was born in Nenagh.I also received a document from a distant relative which states that some of the children were born in Clare, Ireland. It's possible Charles (the father) was born in Donegal.

I recently found an 1851 census taken in Ayton ,Scotland which shows the family lived there before 1850. Charles , the father, was not on the census, so I am not sure if he died before 1850, or just stayed back in Ireland when the family left.I am guessing they moved there around 1845. They ended up in Newfane, New York in 1855. If any of this rings a bell, Iwould truly appreciate information to help me find other places they may have lived.
