Where's Mummy?

My wife, whose enthusiasm for home education has always been, I am sorry to say, a little muted, often remarked upon the absence of mothers in pictures of home educated prodigies. She felt that it indicated something about the nature of the sort of traditional home education which produced offspring capable of studying at Harvard  at the age of 6. We used to examine news cuttings, desperately trying to spot the mothers; a bit like 'Where's Wally?'. Here are a few examples:

The first of these is of course Arran Fernandez, the second Ruth Lawrence and   the third, Judith Polgar.  In each of these well known cases, you could look at a hundred pictures of these children without spotting their mummies! I don't know whether or not this says anything about the nature of highly structured home education. It is very true that my own wife is conspicuously absent from any newspaper articles, clips on Youtube and suchlike, dealing with my daughter and her education.
