Further Refined Topic Ideas

My topic is going to be an analysis of the evolution of the American frontier and how it came to embody the American West, specifically California, in the post-WWII era of the 1950s, 60s and 70s. The main figures of my argument are going to be the suburban residents of Orange County in the post-war era but I will also bring in some important historiographic figures such as Frederick Jackson Turner and political figures that embody the movement such as Ronald Reagan. I would also like to study some of the major figures in Orange Country during the era but at this point I need to do more research into who exactly those people were and what was their function in the community.
I realize that I can take this foundational idea and go any number of ways. The sources I can uncover and find are going to be instrumental in determining how I proceed. To be more specific about my possible directions, I am going to attempt to frame post-WWII Southern California as the frontier described by Frederick Jackson Turner. Turner laments the death of the American frontier and predicts the end of political innovation and freedom on the frontier, but what happened in post-WWII Southern California was the political change that Turner believed to be no longer possible. I would like to find some key figures, specifically women, who migrated to Southern California from the Midwest following WWII and I would like to analyze their role in the movement and analyze not only how their experience was shaped by their migration, but also how they were able to forge such a movement given their position in the social order.
I am cognizant of the possibility that I won’t find a strong narrative for specific individuals in Southern California, in which case I will attempt to follow political, community and religious groups. I also need to do research into an array of secondary sources that will help me develop the foundation necessary to proceed with any type of detailed argument regarding specific people or groups in Orange County. I have already read Suburban Warriors by Lisa McGirr, but now I need to go back and hopefully I will be able to find some of her sources and also hopefully I can do some looking to find secondary sources that either McGirr relies upon or that have been published more recently and rely heavily on McGirr.
