If you are interested in studying the members of an ancestor's community, then you should use the resources of two societies:
The Society for One-Place-Studies. They have a blog, a Facebook group and a Twitter feed.
One-Place Studies. They also have a blog (called Latest News) and a Twitter feed.
As opposed to pure genealogical research, these organizations promote the study of places more so for the purpose of social science. The participants go through town registers listing births, marriages and deaths to put together the relationships and social history of a whole town.
These societies provide information and resources and other people doing similar community research with whom you can learn from and share techniques.
