Hi, nice to meet you as well and yes I am in NZ after living for some time in Aus. My Grandfathers mother was Mary Ann Davey who married Alexander Cormack in Lawrence (Tuapeka) which is in Otago NZ. Elizabeth Edwards, who married in Castlemaine, Christiana, Mary Ann and Martha all came to Lawrence with William Henry and Mary Ann Luke. Christiana Bloxham, Mary Ann Cormack and Martha Uren were their married names. William Henry and Mary Ann Luke were well respected in the district, both Wesleyan's as mentioned, William was head of the Temperance Union and Mary Ann a midwife. I have recently found (what I think) is their grave, unfortunately the rather elaborate headstone has fallen over face down but I am planning to have it restored in the near future. I have also found the grave of Christiana Williams (a daughter of Emma Mary) in Moonta SA and traced Emma Mary Williams to Broken Hill where I believe she is buried. I do believe Henry Davey passed away around the same time Martha was born mainly because his name has been carried on down through the family, one of my Grandfathers brothers was named Henry Davy Cormack for example, which would be unusual if there was another reason for his disappearance. I don't spend much time on Internet Genealogical sites but am on Facebook if you wanted to drop a line it would be great to hear from you.
