Lu & Althea,
thanks for your input. I am in the process of doing exactly what you suggest, Lu. I have certificates on order (the 3 week wait to process them is a pain) for all manner of events registered in NSW.
The dates I've been given for the birth of Edith just do not match anything else I've got.
IF Edith was born in 1874, then the family must have moved to Aus before her birth.
Memoirs of my G-Grandfather put their departure from Timaru at 1871. He'd have been 9 or so at that time. Their departure from England was 1869. No records on passenger lists, just the memoirs as yet.
I have a copy of a typed transcript from his notes - yet to see the original, but hope to do so sometime later this year when I visit the custodian.
Frustrating? Yep, but the main frustration is in the lag time between finding what "might" be an important souirce and its arrival.
I really do appreciate the chance to verbalise these things here, as the act of typing something challenges the sequence I hold in my brain (such as it is

) and forces me to the records rather than my (quite faulty, at times) memory.

Cheers
John
