| Biographical data |
| Name: O'Sullivan, John L. |
| Born: |
| Died: |
| |
| Notes: |
| The Chess Monthly of Mar. 1860 (p.85) has 'J.S. O'Sullivan'. The Era of 9 Nov. 1862 (p.13) has 'Colonel Sulivan late American Ambassador at the Court of Lisbon'. I presume that this should be Colonel O'Sullivan. |
