I'm in Brisbane and also researching Arnotts
My ancestral line is from William Arnott b 1785 married Agnes Nicoll b 1789.
Thomas Arnott b 1816
Thomas Arnott b 1843
William Arnott b 1871
Mary Clark Arnott b 1897 (my grandmother)
They were mostly coal miners and lived in Fife but may have moved around in later years.
Anyone connected to these Arnotts in Australia, I'd love to hear from you.
Thanks Lorand
