Daguerreotype of Edmund and Eliza's son James Ronalds (1834-1891), who died in Australia
Edmund (1790-1874) was Sir Francis Ronalds' closest brother in age and they together ran the family cheesemonger business in Thames Street, London, until Sir Francis and his mother "retired" in 1814. Edmund continued in business for another 40 years and served as Master of the Drapers' Company, one of the Twelve Great Livery Companies in the City of London.
Edmund and his wife Eliza's 12 children led diverse lives. Two married into the Greg cotton-spinning family near Manchester and another spent her last years in Algeria. Five migrated to New Zealand, where letters describe their struggle to support themselves. The two girls wed Atkinson brothers - a third brother, Sir Harry Atkinson, went on to become Premier of the Colony of New Zealand.
Edmund and Eliza's eldest son obtained his doctorate in Germany and was appointed Professor of Chemistry at the Queen's College, Galway. With their shared technical interests, Sir Francis and his nephew Dr Edmund (1819-1889) were very close. Two of Dr Edmund's sons later wintered each year in Florida; Dr Tennent Ronalds (1859-1924) hunted and built a private golf course on his Live Oak Plantation and both eventually died there.
