Hello Linda.
When I started this post I used extensively the Hugh WALLIS IGI way of researching the LDS held photos, taken from the original parish church registers, and their IGI transcriptions used for indexing etc.
I was able to search each christening, plus marriage banns and marrage records, of churches in the environs of Glasgow, where NZ records and newspapers suggested the emigrants had come from. In my case I had already paid at the Mormon Temple in Templeview Hamilton, to import rolls of film not already held there, that held records about my Gt Grand Parents, and their siblings etc. Today these images are also available from Scotlands People. The official site for historic records.
The Hugh WALLIS way made it relatively easy, to broaden my search to nearby churches and parishes, to further my research into the extended families that the NZ emigrants, of interest, left behind. [Transcribing leaves a lot to be desired, being able to view the ORIGINAL record is priceless, as it can hold a key.]
I am not sure that the Wallis option is now available, or if registration and frees are applicable before access can be gained to the records.
TALKINGSCOT a genealogical forum specializing in research and the historic Records of Scotland, has some very experienced helpers, just like RootsChat.
Happy hunting.
Alan.
