Split in Two?

Is the town or village where your ancestor lived split into two counties or townships? In the United States, being in a different county should mean that vital and property records are filed based (usually) upon the county location. If a town or village is split among two townships, it can also impact the enumeration district used for the location in the census as well.

Always know the boundaries and see if the "splits" are making it a "pain" to research your ancestor.
