The is a urban myth story in the Netherlands about a Mien Jeuken who was married with a Billekens, so her married name became Mien Billekens-Jeuken, which means something like "My buttocks itch".
"Now imagine that..."
The story is based on fantasy. On 7 December 2005 I received an email from Gerard Jeuken. In his youth he lived in Sevenum and was a friend of my uncle Theo Billekens. Gerard's mother's name was Mien Pouwels. “Imagine if your mother married my father, she'd be called Mien Billekens-Jeuken"And that's how the story was created:

As a result of this mail, the two old friends got back in touch with each other.
Or an alias during World War II
"On October 28, 2025, I received an email from Leo R., who pointed me to a completely different origin — namely, to an alias used by chaplain P.G. van Enckevort from Venlo, who, together with other clergymen, provided assistance to people in hiding during World War II.
In Deel 7 van Het Koninkrijk der Nederlanden in de Tweede Wereldoorlog (Volume 7 of The Kingdom of the Netherlands in the Second World War) Historian Loe de Jong states the following on page 736:
““Chaplain Van Enckevort adopted a new personal identity and, under that name, was accompanied by a woman named Wilhelmina Jeuken, who was listed among the collaborators as ‘Mien Billekens-Jeuken’.”“.
In its May 4, 1985 edition, the newspaper Trouw published the article titled ”De kerk in oorlogstijd: doorgeefluik naar de illegaliteit (The Church in Wartime: A Conduit to the Resistance)” ook melding van gemaakt:
““The Dutch Catholic clergy officially maintained the position that clergymen should not hold leading roles in the resistance. This did not prevent many priests and chaplains from encouraging their parishioners to help those in hiding. Within these circles, the fictional figure ‘Mien Billekens-Jeuken’ emerged. ‘Billekens’ was the alias of Chaplain P.G. van Enckevort from Venlo. Using a forged identity card, he assumed a wife named Wilhelmina Jeuken, who soon became known in informal circles as Mien Billekens-Jeuken.”“
In search of...
But the idea that this person would have really existed quickly makes a smile appear on the face. In August 2000, the newspaper De Limburger was even on a quest to find someone who knows or has known Mien Billekens-Jeuken.

carnival song
Also in Venray, a village located next to Sevenum in Dutch North Limburg, the story of Mien Billekens-Jeuken is known. Wim Smits (probably) turned it into a carnival song, which was performed by the Venrayse Hofzangers in 1965:
Mien Billekes-Jeuken, Mien Billekes-Jeuken,
Zo hiet mien Mien now al die joare ien d’n trouw. -- (That's the name of my wife since all these years)
Mien Billekes-Jeuken, Mien Billekes-Jeuken,
want Billekes, dat ben ik, Mien Jeuken is mien vrouw. -- (as I'm Billekes, and Mien Jeuken is my wife)
Umdat Mien: Jeuken, en umdat ik: Billekes hiet, -- (because Mien is called Jeuken en I'm called Billekens)
ràkt zij de naam: Mien Billekes-Jeuken niet mèr kwiet. -- (she will never loose the name Mien Billekes-Jeuken againg)
Mien Billekes-Jeuken, Mien Billekes-Jeuken,
Zo hiet mien Mien now al die joare ien d’n trouw. -- (That's the name of my wife since all these years)
