Briefly, Rev. Robert Anderson 1807-1872. Scarva St. Banbridge 1830-1872 lic Letterkenny (Co. Donegal) 1829
"Letters of Administration of the personal estate of Reverend Robert Anderson late of Banbridge County Down Presbyterian Minister deceased who died 27 February 1872 at same place were granted at Belfast to Mary Anderson of Banbridge aforesaid the Widow of said deceased."
An Ancestry tree gives his wife as Catherine Susan Nolen which is incorrect.
So far have only found 1 daughter, Mary whio married Rev. John Waddell.
"The Rev. John Waddell was born at Ballygowan in 1839/40, youngest son of James Waddell. He was minister of Anaghlone 1868-76 and of Newington Pres. Church Belfast 1876-1915. He married
Mary ANDERSON, daughter of Rev. Robert Anderson above. They had 4 sons and 3 daughters, of whom 2 sons and 1 daughter died during their youth.
Two of the sons became Presbyterian ministers, the Rev. John Waddell of Fisherwick, Belfast, and the Rev. Henry Cooke Waddell who is buried here."

Have more on Waddells which I won't post just yet as Rev. John's wife Mary Anderson may not be connected. It was not uncommon to name sons after a minister.
