We've got 4 Elizabeths in our family & I'd love to call any future daughter the same but with a nickname that isn't already spoken for. Across 3 generations we have Lilly, Liz, Betty & Beth. I rather like Betsi (the Welsh spelling, but we no longer live in Wales), Lissy (too cutesy?), Bess (too old fashioned?) but have only just discovered that Liesel could be used as a nickname so I'm rather liking that at the moment!
Love Zab. That's definitely going on the list of shortenings that DH will veto instantly!
