Herbert and Bland Families

Does anyone have any information on the Herbert and Bland connections (especially John Bland born December 13,1758 or his son Nathaniel Bland born 1788 died 1859)?I would certainly like to her from you.John Bland marrried Jean Heron born about 1773, christened November 30,1766. Nathaniel Bland married Mary King (born in England born 1801 and died 1877). It is possible that Nathaniel Bland and Mary King married at Saint Martins in the Fields, Westminister, London, England.Nathanial Bland was born in Balmaclellan, Kirkcudbright and in the 1851 Census was listed as living at High Street, New Galloway, Occupation:Burgh Officer/Taylor.At that time, he was 63 years old.He also had a daughter Agness Bland age 13 living with him and his wife Mary in 1851.Nathaniel and Mary Bland also had a daughter Catherine Dalziel Bland who was born 1825 and died 1891.She married Robert Garrett born 1822, Castle Douglas/Kelton.I have received information that this family was related to the Townsend family, Herbert family, Lindsay, Findlay, Nisbett, Wylie, Love, Graeme, etc.If you can be of help I would be so grateful to hear from you.
