• Land records are a valuable source of genealogical and historical information. Records documenting the sale and ownership of land may cite the kinship between parties or provide other vital records information. For example, a deed may state that a father sold land to his son or include the birth name of the buyer or the seller's wife. Land records may infer the approximate date when a person moved to a town or when a building was erected. They may also include the residence of the parties, if they did not live in the town where they were buying land.
