Looking for Loudon from New Zealand Ireland and Scotland

Aloha,

I am looking for any info on my Loudon side of the family.

We are spelt this way but have found possible entrys for LOUDEN and LOWDEN.

I can trace them back to Co. Mayo to William Corbet/Corbett LOUDON - his father Charles LOUDEN and his fathar John LOUDEN but there the line stops.

I heard a story growing up that there were two brothers and they were in Scotland and parted company. One stayed in Scotland and the other went to Ireland. I am looking for either sides of the family to trace further back.

John LOUDON was from Ballina, Co Mayo - he was a Yeoman there.

Charles LOUDEN/LOUDON married Elizabeth Charlotte CORBET/CORBETT which I am also interested in finding. I think they married in Cork.

Thanks very much. Aloha Meg :-)
