Cheran ... wasn't sure if you had knowledge of these daughters ??
Does seem there was possibly an attempt to "disguse" precise names of parents (as well as adopting another surname)

I did do a check of records to see if Edwin/Edward WOODHOUSE may have been masquerading as "Mr VALE" (- just out of curiosity). NIL found ... and Edwin WOODHOUSE was NOT found either in NZ Police Gazettes (where "desertions from family" or claims for non-payment of maintenance are often published).
