I found the following entry in a church book:
Parentes Herman Heggeman dictus Voskühler Elisabeth Voskühler
Parents: Herman Heggeman known as Voskühler and Elizabeth Voskühler
The marriage record does not contain the word 'dictus'. It appears in two
of the baptism records, but not all of them. The same priest wrote all
entries. I saw similar entries in the book for other Fathers.
