Thomas Gay is also my great great grandfather through Alice Gay, my great grandmother. Who is your great grandfather? I, too, am looking for information about Thomas as we are traveling to Scotland this summer. I found that he was born in Crail, Fife in 1829. When and why he went to New Zealand, I don't know. I do know that he took the Bessie back to Sydney to sell it where he died in 1865 before Alice was born on Niihau.
Have you found out anything more?
