Very cool, if true

And Erin & Mo have stated a preference at some point

We get called Mo & Erin by nearly everyone and I don't remember ever expressing a preference - and Morin is as prevalent as Errag (that is, 'not very'). Weirdly if one were using my full name, I think 'Erin and Morag' sounds a little better than 'Morag and Erin', but no one ever calls me Morag any more, certainly not in conjunction with Erin.

Ari and Lizzie were always Ari and Lizzie until their LJ happened. Now I'm not sure which I use more. Interestingly 'Lari' is used for them way more than either of our nicknames as far as I'm aware...
