The Spireites have recently snapped-up right-back Paul, but he makes up just a third of a McGinn sibling triumverate and part of an impressive footballing family.
Seeding from Glasgow, 25-year-old McGinn is the middle brother of ex-Sheffield United, Watford and current Wycombe Wanderer Stephen and their younger brother John, currently at Hibernian.
Spireite Paul admits that he's had help in his career from within the family: "Of course, they do help me out," he said. "I was in the lower leagues in Scotland while my older brother Stephen was playing for Watford and others, so I knew what I could achieve.
"He told me to keep going and that I'd get my chance. From then on I've done well, moved through the ranks."
Younger brother John has this year become the first of the trio to gain full international recognition when turning out for Scotland against Denmark, however Paul reveals that weekends are rarely entirely enjoyable in the McGinn household: "It's hard in that there's very rarely a weekend when we all win, it sounds ridiculous but that's the way it is.
"It's hard for my mum and dad as they have to deal with at least one of us moaning on the phone at the weekend, while the other two of us are quite happy. This move now means another journey for one of them every so often."
As if the three brothers weren't enough, the footballing genes have clearly filtered throught the generations, with grandfather Jack McGinn a former chairman at Celtic and president of the Scottish Football Association.
For now, Paul is looking forward to his new challenge in North Derbyshire, and he thinks he's ready for it: "I feel pretty good. I was doing running with my brothers, not knowing where I was going until a week or two ago, trying to keep myself fit.
"Most players I would say look after themselves during the break and very rarely to people come back way unfair - though I'm sure I'll hate coming back for pre-season as much as every other player does.
"There are ambitions throughout the club to improve on last season. You need to start from there and then see how we're looking. We all dream big but there's no point shouting too loud, you just need to work hard and see how we can go."
