Hi Bonita,
Sometimes, some places, the names given the baby were the names of the
godparents. This was pointed out to me by my Dad, son of a woman who was
the first American born child of a Hannover family. His 3rd name was
Ludwig, because his godfather was Ludwig.
So, perhaps, Johann Heinrich Wilhelm was named for his father Heinrich
and for 2 of his godparents Johann XXX and Wilhelm XXX. This one's
hypothetical.
This is a real example:
Anna Frieda Elizabeth Rusch (Frieda is a shortened version of
Friedericka, feminine version of Friedrich)
Sponsors: Fred Labs, Elisabeth Rieckmann, and Anna Rieckmann Mueller.
Which name was his "Ruf" name or "called" name? That seems to differ,
based on the families that I know of. Sometimes the first or the second.
Not often the third.
