I knew Bronwyn in pre-school in Australia & we later caught up again as adults in our 20s and 30s, but we eventually lost touch after she moved to the States. I was thinking about her today as I was looking through some old photos & thought I'd try to track her down - your question came up in a Google search. I haven't found her yet, but FYI she had twin daughters, Madeleine and Sasha, & you might be able to find her through them.
If you succeed, can you let me know? Thanks, Cassandra Parkinson (I'm in Sydney, Australia). (I've followed you as well).
