I'm looking at some census images from 1860--and think I might have figured out a set of "married females" living in an 1860 household. Links to full images are at the bottom of this post.
Part of the problem is that the name of the female above Matilda has a name that is difficult to read.
The census entry below, also from Macon County, Missouri, and taken by the same census taker contains a Jane Green.
The question is--is that 26 year old in the Wesley Jones household also a Jane? The first letter in the "Jane" in Wesley Jones' household doesn't look quite like the other "J"s, but it seems reasonable.
I think I have the answer and we'll lay out the case (complete with citations) in issue 52. Like most situations, it's not overly difficult, but it wasn't solved in five minutes either.
The full images can be seen below.
