An index of RN personnel from the early 1900’s until the inter war period of the 1920’s including the whole Great War.

From 1907 until October 1925 those joining the Royal Navy were allocated number is series of blocks with prefixes denoting the ratings classes.

Prefixes and their meanings:
Knowing the Branch of the Royal Navy your ancestor was in gives a very good indication of where they may have served on a ship and what their daily working life would have involved.

It is also notable that within this index only those numbers from 1907 until 1908 have no prefix, after 1908 as number blocks were in danger of spilling over into another branches allocation a prefix letter was added, so if in doubt -the letter prefix is the best indicator of a serviceman’s branch of the RN.
