Family history says Frederick John Briggs b. Abt 1839 in Newmarket ( according to 1881 census) but in Lee, Kent (according to 1891 and 1901 census) was originally Frederick Biggs. He married Julia Gibbs in 1865 in Gosport Hants when he was in the Army based on the Isle of Wight. I cannot find ANY birth record for Frederick John Briggs but then I cannot prove he changed his name! His marriage certificate gives his father's name as BRIGGS but as he was not a witness I do not know if he was actually present. Does anyone know anything about this man please??
