Hi Paddy
I've since found out that Charlotte Wilson married Matthew Tutty (1863-1923)- but do not know his ancestry. They remained in Ireland - six children. Charlotte's parents (and my GGgrandparents) were John Wilson and Mary Ann Finlay.
Not much success with my Wilson ancestry (have Finlay), but have seen references to Frances Wilson. She is not formally linked to my Wilson line so far.
Some Tutty's listed in Aust BDM's. An Edward Tutty had parents of Thomas Tutty and Frances Wilson - died Victoria 1964 aged 75. Your Ggrandparents? I believe another child married a Hanbidge in Wicklow.
Was thought that Elizabeth Mary Tutty (known as Polly)may have emigrated to Australia, but don't know any more about her.
Hope this may help. Contact direct if need more.
