Have you considered that your ancestors may have strayed? If you are looking without success in a known area, then perhaps they strayed from there to another state or country. A "stray" is anyone who is married, lived or died away from his/her place of birth. Imagine how many Australians and New Zealanders down through the last two centuries are strays!
This collection contains two volumes: 1987-1992, and 1993-1998. Together, you can find approximately 4,500 strays collected from a variety of sources and mentions people from throughout Australia and New Zealand. It's a valuable genealogy resource for anyone searching their family history or building their family tree.
