My grandfather (my father's father} Charles Bearpark Harper I understand came from the UK and worked as a tea planter at Dooars Darjeeling. When Charles Bearpark (Harper) retired he migrated to Rowella West Tamar Tasmania. My father Thomas Harper had a Brother Frederick Harper, who went to the UK and lived in Bootle, Liverpool. His sister Marjorie Beaurepaire Bearpark (Harper) was still in Kalimpong India from what I know. The name "Bearpark" was dropped and my father Thomas and his brother Frederick used only Harper.
My mother's (Myrtle Harper nee Hutchins) grandfather Thomas Hutchins came from Shipton Mallet, Somerset UK. He came to India around 1795. He enlisted in Bath on 17 May 1815. Embarked on the "Marquis-on-Huntley" on 22 December 1815 and landed in Bombay India on 16 May 1816.
