He was born on the Isle of Mull in Argyllshire and migrated to Sydney in 1838.
He worked on a Bathurst farm before going to the California gold rushes, returning to Australia in 1851.
In that year he married Margaret McLean, with whom he had nine children.
In 1867 he was elected to the New South Wales Legislative Assembly for Orange, but he did not re-contest in 1869.
