Hello, This was discussed on another List a few weeks ago. Since I belong to about 100 Lists, I don't remember which one, and I need to be vague in my response. But, the gist of what was discussed is that you can call a woman in your home "a mother-in-law" even if she isn't. In general, you need to remember that, when people are chatting with the Census taker, they can tell the Census taker anything they want.

And, please remember to check the on-line auctions for for your surnames and place-names.
