A special election was held in on October 13, 1829, to fill two vacancies in Pennsylvania's congressional delegation before the first session of the 21st Congress.
The vacancies had been caused by the resignations of Samuel D. Ingham (J) who was chosen as U.S. Treasury Secretary and George Wolf (J) who was elected Governor of Pennsylvania[1]
As the 8th district was a plural district with two seats, both empty, this election sent two people to Congress, bolded here for clarity.
| Candidate | Party | Votes[2] | Percent | |
|---|---|---|---|---|
| Peter Ihrie, Jr. | Jacksonian | 5,602 | 27.2% | |
| Samuel A. Smith | Jacksonian | 5,168 | 25.1% | |
| Nathaniel B. Eldred | Jacksonian | 4,993 | 24.3% | |
| George Harrison | Jacksonian | 4,822 | 23.4% |
Ihrie and Smith took their seats on December 7, 1829, the first day of the First Session of the 21st Congress[1]
