Kevin O'Keeffe has lost his seat in Cork East, with his Fianna Fáil running mate James O'Connor taking his place in a huge shock for the O'Keeffe political dynasty.
The final results came through at Mallow GAA complex at 2am, after a marathon count.
On the eighth count, O'Keeffe, from Mitchelstown, lost his seat with 9,078 votes, with Killeagh's O'Connor becoming one of the youngest TDs in the country at just 22 years old, with 9,731 votes.
There was joy and relief for Labour's Sean Sherlock and Fine Gael's David Stanton when they made it through in the same count.
Sherlock's total vote was 11,237, giving him the second seat. Stanton secured 10,309, including transfers, to bring him over the line.
Earlier, Sinn Fein's Pat Buckley was elected on the first count, after topping the poll with 12,587 first preference votes.
Following his election, Deputy Sherlock said: "Government formation is something that will realistically, in my view, have to involve Sinn Féin and another or other parties.
"I just want to say that we have to recognise that mandate and there are so many issues in this country that we all need to start bridging the political divides to start working together."
In his victory speech, Deputy Stanton said it was his sixth election on the trot.
He said the focus now is on creating a strong and stable government, which he said the country needs because it faces serious challenges nationally and internationally.
He added: "It is important that we are all responsible in this regard."
Following the count, James O'Connor said he was deeply honoured to be one of the youngest candidates to be elected to the new Dail.
The makeup of the Cork East constituency for the next Dail will be decided in the count that is currently underway.
