| Biographical data |  | 
   | Name: Jago, Alfred Thomas |  
   | Born: 1826 |  
   | Died: 28 Mar. 1883 |  |  |  
   | Notes: |  
   | The Field of 16 Dec. 1876 has 'A. Iago', and the Westminster Papers of 1 Nov. 1876 (p.123) have 'Iago'. Alan McGowan send records of baptism and probate. The baptism record is dated 24 Sep. 1826, so I am guessing that he was born in that year. |  |  |  |
