The database of surnames in the Netherlands has a new home. It is now maintained by the Central Bureau for Genealogy and available at cbgfamilienamen.nl.
In the database, you can look up a name to see how popular it was in 1947 and 2007, and where those people lived. In many cases, there will be a description of the origin of the name and literature references to publications about the name.
Johan Thorlmohlen (spelling on passenger list) & wife Marie migrated to Australia (Queensland) from Hamburg on the ship Lammershagen and arrived 7.9.1871.
The family believe he was Dutch. His first name is? keeping in mind the bavarian Kingdom rule around this time.
Please advise as I am writing a book for the family.
