I note you are a decendant of a Jeremiah Lamplough that lived in Australia. I am a decendant of a George Robert Lamplough who ended up on the West Coast of the South Island of New Zealand. I'm pretty sure George and Jeremaih were brothers (parents the same as you have listed).
I was wondering if you had any other information on Jeremaih's and George's brother and sisters. Please email me if you do.
