Already at the club in the days of St Sidwell's United, Frederick Aplin played in the newly-renamed Exeter City’s first match against 110 Battery Royal Artillery on 10 September 1904.
There is nothihg to suggest that Frederick made any more first-team appearances after the initial fixture although he remained with the club as a regular member of the reserve team.
It is understood that, at one time during the St Sidwell's/early Exeter City years, that Frederick was captain of the 2nd XI with an Albert Aplin as vice-captain. They are likely to have been cousins born within a few months of each other.
The 1901 census shows a Frederick Aplin (then aged seventeen, born Exeter) living in Bartholomew Street and working as a plasterer. Further public records show a Frederick Aplin resident at the West of Eye Infirmary on Magdalen Street, Exeter in 1939 ahead of his death in 1940.
