Re: Great Grandfather served in India and maybe Boer War...help!!
Did he have a middle name? Did he end up in Australia and if so do you know when? There are two separate databases, one for Australian and one called 'Soldiers of the Queen' for UK-based regiments which served in S Af.
As far as the photos go they can be posted in the Old Photos board.
There are two ways of putting them there. One way is to attach a file from your own computer. But to get better quality photos it's best to upload them to some site like Photobucket then paste the img link from the site where the photo is stored.
Others here can give you further tips in the Old Photos board.
The SOTQ index aims to narrow your search for Boer War veterans but do not expect too much from it - at this stage it only covers something over half of the 500,000 Boer War soldiers and nurses on the British side. Moreover, many entries just provide initials rather than given names. Hopefully that could still make your haystack a bit smaller.
