My own direct ancestors came from Derry.
As far as I can trace back, my GGG Granda Dennis was born in 1833 (not sure which parish). His parents were Hugh Quigley & Mary McGuire.
There is a John Quigley born in the family 1867 Greenock. To Dennis Quigley & Sarah McGinnes.
Can't find any info of any of the other members of the Quigley family since 1833.
