Dean Shiels has become his father Kenny's latest summer signing after joining Kilmarnock on loan from Doncaster Rovers until January.
And he could soon be followed to Rugby Park by 18-year-old Linfield midfielder Jude Winchester.
The 26-year-old Shiels, who has nine caps for Northern Ireland, joined Doncaster from Hibernian for £50,000 in February 2009.
But he found himself relegated to the bench at the tail end of last season.
Rovers have this summer signed 20-year-old midfielder Kyle Bennett from Bury for an undisclosed fee and have now allowed Shiels to head for Ayrshire.
Shiels, who began his career with Arsenal before joining Hibs in 2004, is available to face Motherwell on Saturday as Kilmarnock host Motherwell in the Scottish Premier League.
Meanwhile, Winchester is poised to sign for Kilmarnock after impressing on trial.
His twin brother, Carl, has already made the move to the British mainland, having signed for Oldham Athletic in June.
That came a month after he made his Northern Ireland debut against Wales.
Kilmarnock manager Shiels has already returned to his homeland to bolster his squad this summer and left-back Rory McKeown repaid him with a spectacular goal against Dundee United last weekend.
The 18-year-old, who arrived from Ipswich Town, said: "I knew Kenny as a kid.
"He was the county development officer for Antrim. He brought me into that programme and he was always good to me.
"Whenever he heard I had been shown the door at Ipswich, he was straight on to me and invited me up for a trial."
McKeown was at Ipswich for two seasons and was a regular for the reserve team.
"Paul Jewell came in and I didn't get the pro contract," the defender said.
"He's an experienced manager and he knew what he was looking for. I obviously didn't impress him enough to get a contract, which is fair enough.
"I was disappointed, I wanted to stay down there and a lot of my friends are there.
"But Kenny has given me the contract and I can't complain. I'm looking forward to a good season up here and hopefully showing Kenny what I can do."
