I'm coming up against a bit of a problem in the timeline of my WIP. As it stands, the MC is 23 years old in the year 1961. This means she had to have been born in 1938, which is one year before WWII began. I have been planning on using the 1967 Tasmanian Bushfires as a catalyst event in my plot. To use this historical event in the way I've planned, my two MCs must be 23 and 18 in 1961 (which they currently are). HOWEVER. I have also just lit upon an idea that would absolutely transform some crucial character building and backstory setting up for the MCs' parents, as well as to create the perfect doorway to explore social and cultural elements in post-WWII Australia. This would require the MCs' mother (Esther) to have been a war nurse from 1941-1945. But married mothers couldn't work as nurses in the war. But if Esther doesn't have her daughters until after the war, they won't be old enough by 1967 for the events with the bushfires to work in my plot. So my dilemma is this: I thought I might just pretend the '67 bushfires didn't happen and create my own bushfire event when I need it in the plot. But the '67 blazes were a devastating natural phenomonon that killed hundreds and took even more homes and farms. So if my characters live in that geographical area (southern Tas) and live through 1967 without a whisper of fire, it just seems inauthentic, incorrect, ignorant and disrespectful to history. I can't manipulate history's timeline and make the bushfires happen ten years later (when the girls are the right ages) because the firefighting equipment and the emergency procedures/building regulations etc would all be so different by then that the bushfires just wouldn't play out in the same way they did in '67. (And anyway; is changing the date really any better than cutting the event altogether??) I can't set the story earlier because my plot relies on the upheaval surrounding the Vietnam War protests and White Australia policy changes, which were only sort of really starting to gain traction in the early '60s. I can't set the story later because my plot relies on social stigma and secrecy around unwed motherhood, the pill and abortion, topics which were already starting to relax and become less stigmatised by the mid '60s. I don't know what to do! Thanks for reading this far. I'd be so grateful for any feedback you guys might have. Feel free to ask questions if I've been unclear about anything!
