The BAILLIE family came to New Zealand on the Gothic in 1904 and took up residence in Dunedin. Elizabeth is shown as being at school there in 1910, and her parents lived there at the time of her marriage.
She presumably then moved to Wanganui with Percy. According to my information they had two children Alexander Sloan Baillie WELLER and Donald. Alex was named after Elizabeth’s brother who died in France in 1916.
