Thomas Harmer is possibly the same Thomas Harmer whose birth was recorded in the December 1877 quarter at Lewes and who, in 1901, was recorded on the census for that year living in
Brighton and working as a
machine hand at a brass factory. His
place of birth is stated on the census as Lewes.
He could also be related to John Harmer, (possibly as an uncle) whom Chailey Parish Magazine also notes as serving his King and Country.
