Service records & Depot Companies 24th Foot

Having copied most of what I require from the pay-lists for the 24th Foot, I am trying to complete other avenues of research to add more detail. One area of which is the surviving service records of the men. I have downloaded the Officers direct from TNA WO 76 series. I am now looking at the Other Ranks WO 97 Series.

According to TNA Discovery this is available on Findmypast which I have a subscription to. Despite various searches the only records showing are from the WO 22 & 23 Series (I've copied WO 23/38,47 & 57 parts plus slowly working through the individual entries for others).

Has anyone ever downloaded WO97 from here? I am aware that the earlier parts are in Regimental order and latter years are individual alphabetical format. Is it better to look in TNA?

My second point is the whereabouts of the depot companies pay-lists April 1870 to December 1872 (if they exist). The Depot moved from 9th Depot Bn to 1st Depot Bn 28th February 1870 in Chatham and then to the General Depot Chatham from the 1st April.

All previous pay-lists are attached to the corresponding Main Battalion pay-lists but those at Chatham are not, only showing again at the start of the 25th Brigade Depot in April 1873. I have looked in various Regimental lists of units who were based there at that time to no avail. Martin Everett has kindly shown me the Census for 1871 so they are most definitely there along with  a half dozen other depots. (Thanks again). There are no documents listed for Depot Battalions in Chatham in that time period.

Could it be possible that they MAY be listed with the Royal Engineers?

Any ideas would be appreciated.

Cheers, Bill
