Hi John,
I've also got ENNIS in my own tree, but my John had died in NSW IN 1840's and among his beneficiaries was my great great grandmother, who incidentally married a NSW born chap whose father was Spanish. Its not easy searching for Portuguese or Spanish records

but I agree that it would be wonderful to go back another generation
I've got photos that seem to show beautiful complexions, dark straight hair, and wonderful smiles. I've been told that there's (expensive) DNA tests that can show indicators for Mediterranean origins, but my piggybank doesn't stretch that far.
Cheers, and I hope you enjoy RChat and join in with the discussions. I'm sure you will be most welcome.
JM
