You might, if you can get hold of them, consult the first-hand accounts by Ryder, ‘Metcalfe’ and especially Waterfield, which I mentioned on the ‘Good conduct Pay’ thread. There are interesting comments on wives and children relating to topics such as: separation on embarkation of a regiment, voyages to/from India by sea, ‘forced’ marriage of young girls to much older NCOs, implied mass infidelity by wives of another regiment with men of the 32nd (while their husbands were serving elsewhere, of course.) Waterfield, who comments on these topics, never indulged in such practices, naturally; indeed he seems to have been a misogynist, if not an out-and-out misanthropist, not recommending marriage to serving soldiers.
Interesting is the total lack of mention of liaisons/marriages with Indian women; many hundreds of adult males over 12 years in India with the 32nd and nothing! One suspects that this was a taboo topic.

My feeling, though I haven’t been able to research it, is that (apart from the obvious attraction of a bounty) many of the men who volunteered to other regiments, especially when their’s were due to return to Britain, did so because they had acquired Indian wives/children who would i) not have their passages ‘home’ paid ii) would be decidedly unwelcome back ‘home’. Swiney (
see below) hints as such when he mentions the ‘European’ women of the 32nd massacred at Cawnpore (Kanpur.) Metcalfe certainly waited till he got back to Britain (Ireland?) before very rapidly acquiring a wife, though she gets very little mention in his memoir, not even a name. I suspect that his memoir was dictated to a family member, who would have all the details of family life to hand. Since she seems to have accompanied him to his various postings from there on, I guess that once a wife was ‘on the strength’ she would stay on it for future postings and not be subjected to the lottery.
Again, at least some regiments (I’d be interested in hearing details of others) seem to have taken the education of their children seriously. The 32nd had a Schoolmaster Sergeant, Edward Vaughan, who was recommended for, but did not receive, a V.C., at Lucknow. Mrs (later Lady) Inglis, wife of Lt. Col John Inglis who commanded the 32nd during its later years in India, took an active part in educating and improving the lives of the regiment’s children. Ryder also states that he learned to read and write in the army, his only service being with the 32nd. On the other hand, Metcalfe’s discharge papers state that, after a full career as a professional soldier with the 32nd , he was ‘not in possession of a certificate of education’, on retirement.
Whilst on the topic, I wonder if anyone can come up with info. to ‘beat’ the 32nd’s sad claim to be the ‘most massacred’ in terms of the women and children. The numbers, from the regiment’s depot coy., who died during the two-week siege of Cawnpore or were massacred after the surrender were ‘45 ‘European’ ladies and women and 54 children. ‘ (Swiney p.182.*)I think there were 4 ‘ladies’, whose deaths were obviously more regrettable than those of mere ‘women’

About 30 women, 4 ‘ladies’ and an indeterminate number of children were with the bulk of the regiment during the Siege of Lucknow and I’m trying to identify as many of these as possible, without much luck so far (see my posting on the ‘Original Defenders…’ thread of the ‘Mutiny’ section.) Any help gratefully received.
Whilst the number of women and children who died/were killed on the retreat from Kabul (1842) may have been greater, they ‘belonged’ to a number of units, but perhaps there are cases of mass deaths of wives and children of an individual unit from cholera or other diseases, especially in India or the West Indies.
