Peter Paul McSwiney (1810 – 27 February 1884) was an Irish politician and businessman.[1]
He was born in Cork city, son of John McSwiney, part of the prosperous catholic middle class in Cork.[1] In 1852 McSwiney formed a partnership with draper George Delaney to open a store on Sackville Street, Dublin.[1]
He was elected to Dublin Corporation in 1860,[1] and served as Lord Mayor of Dublin from 1864 to 1865, and again from 1875 to 1876.[2]
McSwiney proposed the placing of a statue of Daniel O'Connell (a distant relative) in Sackville Street, and on 8 August 1864 he laid the foundation stone.[1]
