| Biographical data |
| Name: Duffy, Patrick Thomas |
| Born: 14 Sep. 1834 |
| Died: 17 Apr. 1888 |
| |
| Notes: |
| Sergeant gives date of death as 11-04-1888. Gaige gives date of death as 17-04-1888. The Chess Players' Quarterly Chronicle of Feb. 1869 (vol.1, p.155) has 'P.J. Duffy', clearly an error for 'P.T. Duffy'. |
