[Ger-Poland-Volhynia] Wilhelmine = Monika in Catholic Goslawice records

[Edelgard Strobel]

In the Catholic records of Goslawice, Konin I found different records where Wilhelmine appears as Monika:

F. i. Wilhelmine Zarn, married Christoph Wolf on Feb. 1st, 1857 in Konin

She has been baptized as Monika in Goslawice  (# 81)

next example:

Wilhelmine Milas, wife of Johann Kaus appears as Monika at the birth of her daughter Luise in 1837 (# 22)

At the batism of son Ludwig in the Evangelical church of Konin in 1839 she is called Wilhelmine again (# 12)

What could have been the reason that the pastor refused to enter the name Wilhelmine?
