Question

G2G: How do I set up a category for German ancestors who migrated to the Hunter Valley in New South Wales?

Answer 1

There are categories already set up for immigrants from Germany to NSW. You'll find them here: https://www.wikitree.com/wiki/Category:New_South_Wales%2C_Immigrants

If you tag your question with Categorization, Immigration, Australia etc someone from Categorization will see your question in their feed.
