Zut! Catlady. Now I don't have a clue which way we are going and Safia has gong to bed (as should I, BTW) and so can not keep us "honest". Glad your squash family are doing well; I believe that the humble courgette, if not bigged up too much by its American brethren, will still recognise that it is part of the squash family.
We had the "year of the courgette" a few years ago when we grew many and they were very tasty.
OK. I'll give it a go, starter for 10: Is a grown up courgette a marrow?
[Ed's comment: I have absolutely no idea of the answer here but can probably research it faster than you can!].
