Extract of Letter from Miss Jane Dare.
"Dr. de St. Felix was attached to the Court of Louis XVI., and fled from France at the breaking out of the Revolution.
He accumulated large property in Demerara, British Guiana and married a Miss Osborne, of Upshire Hill, near Waltham, Essex. Two of their sons entered the Army, one in the 27th Regiment, the other, Anthony, in the Guards.
The former married his cousin, a Mary Osborne, born in 1800, and had three children, Louis, a daughter who married a Mr. Campbell, and Louise Antoinette, who has inherited a little of the property of her grandfather, Mr. Osborne.
Mr. St. Felix, of the 27th Regiment, was very intimate with Prince Louis, afterwards King of Sardinia, who took much interest in and provided for Louis St. Felix, who could only speak Italian and French.
Louis St. Felix paid a long visit to England in 1857, and died at Chamberry in 1859. Louisa Antoinette St Felix was born in July, 1821, and in July, 1840, married Mr. John Julius Dare. Her mother, Mary St. Felix nee Osborne, died at Turin, in 1832.
The Dare's Swiss property comes through Dean Abbott, who was related to the Osbornes."
The researcher finds this statement less than clear, the relationships herein are his best guess ?

Louis married Miss Mary OSBORNE of Upshire Hall Waltham ESS [1490] [MRIN: 473], daughter of John OSBORNE [35116] and Mary TULLOH [35117], on 10 Feb 1820 in St Martins in the Fields Westminster. (Miss Mary OSBORNE of Upshire Hall Waltham ESS [1490] was born in 1800 in Waltham ESS and died in 1832 in Turin Italy.)
