I think I have a cousin descended from your Hutchisons:

Laura Augusta Hutchison (born 1828) daughter of George Hutchison married at Bangalore, India 3 August 1846 Lt. Henry Acton, 4th Madras Cavalry (1824-16 April 1865), son of Lt. Henry Acton (nephew of Sir John Acton, 6th Baronet) and his wife Charlotte Clugston.

They have many descendants, most of whom live in the USA. If anyone can find a baptism record for Laura Augusta Hutchison that would confirm the link.

Best wishes,

William Acton
