Hi Jordan,
I would be very interested to hear about your family roots. I know of one Tichborne line that is in NZ and is connected to the Hampshire lines I am writing about. But there may be others and the Irish connection is possible.
Best if you email me and we can exchange info that way. The Tichborne name is ancient and very interesting. As far as I can tell they are all related!
