Whoever filled in the household schdeule may of course have interpreted the question differently to how it was stated.
Yes, that's true, Valda, but the point I was trying to make was that any perceived barriers to accessing the information may be of our own making

I delayed the research of my mother's first-born child, because I'd read that it could be difficult to access the records, and even then I might not be able to get copies of certificates. In the end, when I did try, I was able to get the certificates as easily as all the other certificates that I'd bought. Much more poignant though.
