The problem is that as with the other side (MSG/CSA) service there is also undercounting and non-duplicate counting. Many MSG names appear multiple times in the MSG and in CSA units. In both northern and southern service it appears that as much is missed as is counted. From what I have gathered studying various early battles there seem to be various examples of early Home Guard who saw action or were killed/captured not being noted. Later non-MSM militia service (EMM, etc.) seem to be even less well documented. Granted these often aren't "Federal" service...and there are some "paw-paw" and other anti-union types that would be counted among their numbers, making the count really skewed. I have a key southern relation/in-law who shows up nowhere that I have found, but was apparently executed (most likely by guerrillas, but possibly/plausibly by jayhawkers). Was he neutral, pro-southern, pro-union? I don't know. His self-described "southern bell" widow married my 1st MSM gggrandfather during the war and moved the growing family (including daughter sired by the previous spouse) to KS postwar...so there must have been a heckuva lot going on in their/her world to make that even remotely possible. What I know of her indicates she wouldn't have moved to KS against her own wishes (I have more sources about her than any other figure of the period...plus my grandmother seems to be the spitting image of her in various ways.)

This sort of thing really needs a rigorous, modern, name-by-name analysis on both sides of the fence (doctoral candidates step up to the task.) I don't pretend to know the count ahead of time. Even with a rigorous count of all surviving records, the result would only be an approximation. Missouri was very complex during the war with Unionists of the radical and conservative blocks going at it with an intensity only exceeded by that directed toward secessionists. And sometimes that line wasn't obvious.

Bruce, as I've commented before, a detailed analysis of the likely "known/suspected" casualties of the guerrilla war would be helpful in understanding the incredibly violent and complex war in Missouri. I figure some grad student/doctoral candidate will tackle this some day. Some census comparisons will most likely be required. And even that will be open to record keeping biases for the tumultuous period and its aftermath.

I don't pretend to have the answers, but I have a growing list of questions.
