hello Minniehaha,
many thanks for those leads.
I've been looking into them, and the manifests, not yet convinced about the plausibility of Amy Hill travelling on the Tongariro. She may have travelled by her maiden name Williams, and at the moment the most plausible is SS Ophir, in 1911. The dates and years are beginning to link together though. I'm ferretting around links for (John) Henry Hill, now I know he came from Birmingham area. Now that is plausible. Some progress has been made even if in a different direction to what I was expecting.
I've been trawling electoral rolls to see where Madkins was in the mid 1900-1909 period, checking to see if she was a domestic within a household, similar to Amy.
The Death (DeAth) surname has resurfaced too after some years, but I cannot find my previous searches.
Many thanks for your research. I'll keep ferretting.
rallenza.
