I've had confirmation back from my Scots 'Ireland' researchers that all of the known Thomas Irelands, descendants of Jean Trotter Ireland, in the right time frame can be accounted for except my Thomas.
Althea, in 1893 it could have been that transit issue. That's the year he travelled to UK. I've been able to get free short term access to worldvital records and also findmypast au to check out various Wise's and 1881 Elect Roll. Found Thomas Ireland, FARMER, in FernFlats, Marton in 1898, Clara Ireland is in Fern Flats in 1896 Suppl as you call. Can't explain lack of my Thomas there. Thomas not on 1881 Elect Roll either - likely a timing issue if he came late 1878. IS on 1897, 1890 Dunedin and 1900 in Wanganui.
Coupled with the Papers Past articles, passenger list info, ITM, Marr Cert, I'm happy to claim Thomas Trotter Ireland as my man. In NZ at least by 1878. I've learned lots and met nice, helpful people along the way

. Thanks to all!

Sue
