I have just spent an inordinate amount of time trying to track down appropriate names for my family. It is late in the evening and I thought I would set myself a relatively easy task. I would do a preliminary web search looking for family names from Marburg, or more generally from Hessen-Kessel.
My first block was that almost all records require a name to start the search. I was hoping somewhere might have a list of family names, out of which I could pick something euphonious (and not related to any of my current neighbours who might take exception to having a perceived fictional embodiment).
I do know that I have to look at archives for “Evangelisches” or Protestants because most German settlers in the Rosewood Scrub were Lutherans. Rosewood has the closest proper (that is, full-time rather than circuit) Catholic church because it is on the plains and near the railway, hence favoured by the Anglo-Irish. The hills were settled by the Germans whose favourite religious pastime seemed to be church factionalism, judging by the number and variety of Lutheran churches.
Back to names, I shall have to devise a strategy to find my way through the web of genealogical information available. Apparently, most people are researching ancestors, rather than attempting historical veracity for a work of fiction. Maybe this is in my favour.
