I've been looking at Thomas and Sidney's likely "passage to India".
I believe their early movements would have been similar:
After enlistment they would have spent about three or four months at the Depot at Northampton in training. After that (the end of 1888 for Thomas, and at the end of 1890 for Sidney), they would have transferred to the 1st Battalion at Warley. On 28th November 1890, the 1st Battalion arrived at Aldershot.
Since both of them were in Aldershot for the 1891 Census, it leaves three possible paths to India for them.
1) Stayed at Aldershot with 1st Bn. until the end of 1891. There seems to have been only one reinforcement ship per year (in November or December each year) travelling to and from the 2nd Battalion who were at that point in "the Straits Settlements" (i.e. Singapore). If they joined the 1891 reinforcement ship they would have transferred to the 2nd Battalion on 18th December 1891, and boarded HMS Himalaya on the 19th December 1891. HMS Himalaya, with 228 reinforcements for Singapore aboard primarily for the 2nd Northamptons, reached Singapore on 2nd February 1892, where they would have stayed for most of the rest of 1892.
On 14th November 1892, the 2nd Battalion finished its overseas posting and returned to England, also aboard HMS Himalaya. Those men who still had overseas time to serve would have transferred to the 1st Battalion on departure from Singapore. HMS Himalaya headed back to the UK via India and arrived at Bombay on 26th November 1892. The newly arrived draft of men from 2nd Battalion joined the 1st Battalion at Bangalore on 2nd December 1892.
Or......
2) One or both of them did not board HMS Himalaya on its draft delivering voyage to Singapore in late 1891, and instead stayed at Aldershot with 1st Battalion until the 1st Battalion was posted onto overseas duty in October 1892. The 1st Battalion boarded HMS Malabar at Portsmouth on 5th October 1892, and sailed to India reaching Bombay on 1st November 1892. They moved inland to their new base at Bangalore arriving there on 19th November 1892. The Draft from 2nd Battalion joined them a couple of weeks later.
Or.....
3) One or both of them stayed in England after 1892, which would have meant a transfer to 2nd Battalion (physically joining them when they arrived back in the UK from Singapore), in which case it's anybody's guess!
I do wonder whether their father's "tradition" of service with the old 48th (i.e. the 1st battalion) meant that they may have stayed with the 1st battalion until the battalion went abroad as a whole, but that is just speculation.... Bearing in mind that Thomas Jnr. stayed with the 1st battalion from 1888 to 1891, he may have followed route (2).
