The first point is be realistic in your understanding of a project. You will need to invest time as you undertake your research and that be a challenge depending on your domestic commitments. As I said previously, the internet has changed the way we can undertake such projects and we can to some degree sit at home, on our sofa or at our desk and work away. You might have an hour a week to spend or you maybe retired and have significant time at your disposal. Whatever your personal situation, do not let how much time you have available effect your plans. Scope out your ideas and perhaps work with others, sharing the workload.
I have always worked on the Orlando study solo. Yet my Butcher study has had intervention from family members and others with connections to various Butcher families. The amount of connection with others will depend on your approach to “advertising” your work, another factor will typically be that a popular surname is likely to have more interaction with others, compared to a smaller study. The Orlando study breaks that theory because it is a large study with limited interactions from others, and it is only in the last few years, since I began writing about the study that I have received contact from other researchers.
I shall leave you to ponder on how you might achieve your project and I will be back tomorrow, looking at ideas for planning a project.
