Hello, thank you for your reply, as far as I know Margaret did have a brother Edwin Sydney Ogilve Gove born 1817 Marykirk, Kincardineshire, died 1886 Fettercairn.
Also a sister Susan Gove born 1804 Marykirk, Kincardineshire, died 1874 Ferryden.
I have Margaret's death certificate , she died in 1871 in Dundee, Angus and her parents were Francis Gove and Mary Ogilvie.
I have not found her birth as yet, but will keep looking ....many thanks
